Cosmo Communicator review: The PDA/smartphone rides again Review

The Cosmo Communicator is Earth Computers’ second endeavor to reinvent the substantially-loved Psion Sequence 5 for the smartphone age in an Android/Linux incarnation. Its clamshell type element involves a slide-out keyboard, and some functions are manageable with out the will need to open up the system. It is an thought that has produced a good deal of consideration, but does this £665.eighty three (ex. VAT, or £799 inc. VAT) handheld personal computer/smartphone have a put in your tech armoury?

Time was when smartphones with keyboards have been a matter. There have been slide-outs, hinged lids, and total frontal (Blackberry-design and style) keyboards. Right before that there was the Psion Sequence 5 (and some smaller variants far too), with a hinged lid defending a monochrome display screen and a slide-out keyboard that was simply planet class. Cell comms was not built-in into the Sequence 5, but it was an great tiny personal computer. I utilised one particular for a prolonged time as a pocket-sized crafting machine. It wasn’t just me: the Sequence 5 was iconic.

Many makes an attempt have been built to resurrect the Psion Sequence 5, and the most modern have come from Earth Desktops. The United kingdom firm’s to start with shot, the Gemini PDA, was intriguing but had its disadvantages. The Cosmo Communicator moves the thought on, importantly which include functionality into the lid, which is a authentic increase to usability. 


The Cosmo Communicator is Earth Computers’ second stab at re-imagining the 1997 Psion Sequence 5 for the smartphone era. It operates Android 9 and Linux (in owing course) on a MediaTek Helio P70 chipset with 6GB of RAM and 128GB of inner storage (expandable by using MicroSD).

This is a major beast as opposed to a regular smartphone. The footprint — 171mm prolonged and seventy nine.3mm deep — is identical to that of a big-display screen (six.5-inch) smartphone, but it is a excellent deal thicker. The Cosmo Communicator actions 17.3m thick at its thickest place, which is the a little raised centre of the lid. It is a weighty system far too, at 326g.

The place the Gemini PDA had a featureless lid, the Cosmo Communicator has a fingerprint sensor, a 24MP camera with flash and a 1.91-inch AMOLED contact display screen. The latter is important to the device’s usability. With the Gemini PDA it was vital to open up the clamshell to do pretty substantially anything at all. Right here, the display screen provides info and caters for some conversation. For case in point, it will show a notification when a textual content arrives in, and you can then faucet the display screen to dismiss it or initiate a response — you have to open up the clam to really style a reply, but when you do so you might be taken suitable to the SMS app.

Incoming e-mail are exhibited in this article far too, and though you can only see the beginning of a message, it might be adequate to encourage you to open up up and reply — once again, when you do open up the clam, the relevant app is suitable in entrance of you producing the method of responding as rapidly and seamless as doable.

Far more than that, there is a fundamental menu on the entrance display screen. The fingerprint sensor is integrated in a compact contact pad. A one push of the pad phone calls up the key entrance display screen, showing time and day, and a number of process icons (Bluetooth, battery, wi-fi and SIM status). Tapping the pad opens a further display screen showing modern phone calls, and it is simple to connect with a selection on the record with a faucet. Small icons make it possible for you to accessibility contacts and a dialpad so you can initiate new phone calls, and when in a connect with there are tappable icons for items like speaker manner, muting and adding contacts into a connect with.

A further display screen receives you into a menu of 8 shortcuts to attributes like camera, video, torch, power and options for the small entrance display screen — you can improve its orientation and brightness for case in point, and even make it possible for it to auto rotate. 

This entrance display screen is beautifully purposeful and its existence in this article presents a major increase to usability as opposed to the Gemini PDA. Legitimate, the numerous interactive icons can be really compact, but it is responsive and I discovered myself fortunately dismissing textual content messages and taking voice phone calls with out opening up the system. 

Open up the clamshell and a total QWERTY keyboard slides towards you. This is the heart of the Cosmo Communicator, and its resemblance to the aged Psion Sequence 5 is no coincidence. Certainly, the designer of the initial Sequence 5 keyboard, Martin Riddiford, had a hand in its generation. The Cosmo Communicator’s backlit keyboard has a softer, considerably less definite truly feel than the Psion Sequence 5’s, but the similarities are clear.

I discovered that some keys failed to sign up with my regular gentle contact, and I had to modify my speed and typing motion a little to compensate. But continue to, I was ready to contact style at about 75 p.c of my regular speed, which is excellent going for this kind of a compact keyboard.

The keyboard intended I could use the Cosmo Communicator for significant doc generation — this overview was composed on it, for case in point. I worked on crafting initiatives though out and about, while I had to be at a table as thumb-typing though standing with the system opened up or seeking to relaxation it on my knees have been both equally unsatisfactory. Even so, I would take the Cosmo Communicator into meetings to produce notes in choice to my laptop computer. It wouldn’t be my continual typing system, but it would be the suitable fit for some instances.

The Cosmo Communicator’s key 5.9-inch two,one hundred sixty-by-1,080-pixel display screen is built mainly to be utilised in landscape manner, but it will rotate into portrait manner to accommodate the point that Android apps are, by and big, built to be utilised in this orientation. Even so, holding this system with the display screen in portrait manner is uncomfortable and unwieldy.

The Cosmo Communicator operates Android 9 with a Cosmo overlay that involves a selection of bespoke apps. LEDIson was shipped with the initial Gemini PDA and authorized callers and notifications to be identified as a result of a sequence of configurable LED lights on the system. It is in this article once again, even while it is redundant because the entrance display screen tells you who is calling, texting, emailing and so on.


Agenda was the Psion Sequence 5’s killer app, and Earth Desktops has performed a excellent occupation of recreating it.

Pre-set up 3rd bash apps include things like Phrase, Excel and Skype, all of which are somewhat more useful. In its personal software program suite, Earth Desktops has also absent to excellent pains to reproduce arguably the killer app of the Psion Sequence 5: Agenda. This diary app supplied a clean up presentation of my weekly diary, synced from Google Calendar, and also has fantastic year planner and regular monthly no cost/busy sights. I also speedily grew to become a admirer of the Notes app, which can capture textual content, photographs, films and voice recordings.

Tapping the essential to the left of the room bar phone calls up a software program menu bar that emulates the hardware-primarily based bar on the initial Psion Sequence 5, providing rapid accessibility to a array of apps. It is arguably needless specified the tappable app shortcuts, but is nonetheless a wonderful bespoke element.

The Cosmo Communicator operates on a MediaTek Helio P70 chipset with 6GB of RAM. This system sent regular Geekbench 5 scores of 296 (one main) and 1471 (multi-main), which are distinctly middle of the road.

You might truly feel that 128GB of inner storage is not adequate, contemplating that 13GB of this is utilised by the process alone. There is a MicroSD card slot for external storage, but using that principles out the device’s second SIM slot. That is a shame, while the system does also support eSIMs. At the very least the SIM caddy is available on one particular of the quick edges of the lid area with the Gemini PDA you had to eliminate the prime of the lid area to get at the SIM slot.

Bluetooth 5, GPS, NFC and 802.11ac wi-fi — the NFC zone is on the lid. There is a three.5mm headset jack, a USB-C cost slot and a second USB-C port for attaching a array of peripherals. Accessories include things like a USB-C-to-HDMI cable (£39.98 inc. VAT) and a USB-C Hub with two USB three. ports, a USB-C connector and an Ethernet port (£44.99 inc. VAT).

Connectivity is a essential ingredient of the Cosmo Communicator’s functionality. It supports Debian Linux, and if you are so inclined the system can be related to a check and an external keyboard and utilised like a Pc. Perfectly, in concept. In point, Linux support wasn’t carried out at the time of crafting — view the support internet pages if you might be intrigued in this aspect of the system. 

The Cosmo Communicator has two cameras: an outward-facing 24MP camera, and a 5MP camera to the prime left of the key display screen. The inner camera operates good for video calling, though the key camera is Ok for capturing fundamental pics, but there is certainly tiny in the way of sophistication in this article. If you will need more than the basics, seem elsewhere. 

On paper, the four,220mAh battery should really deliver at the very least a day’s use, but in exercise battery everyday living was disappointing. The Pc Mark battery test noted just six hours and thirteen minutes, and through testing I utilised 50{fb741301fcc9e6a089210a2d6dd4da375f6d1577f4d7524c5633222b81dec1ca} of a total battery in about a few hours of typing on a number of instances. If you might be significant about using the Cosmo Communicator for every day efficiency, you are going to will need to seem out for charging points through the working day.

The Cosmo Communicator is a further intriguing system from Earth Desktops, and undoubtedly an advance on its Gemini PDA predecessor. When the Linux capability gets to be obtainable, it will have even increased enchantment. Having relatively rapidly keyboard input obtainable on this kind of a compact system is really desirable, and the bespoke apps are properly built and very well realised. The Cosmo Communicator could even swap a laptop computer for some or all of the time, at the very least for some men and women.

Even so, £799 (inc. VAT) buys you a respectable laptop computer, and big-display screen smartphones can be coupled with folding Bluetooth keyboards. This indicates that the Cosmo Communicator may battle to get traction outside a relatively compact area of interest, except if Earth Desktops can discover a way to cut down the selling price tag.
