Anybody seen any for sale? Or is the Cosmo screen the same size as the Gemini's?

Haven't seen any confirmation that screen of Cosmo would be same as Gemini. But I took risk and ordered few Gemini protectors from eBay. Also ordered custom made leather belt case and few universal active styluses. And few USB-C charging cables.

So everything should be now ready for Cosmo arrival...

Apart from the thickness the 2 devices have the same dimensions. I'd be surprised if the screen is not exactly the same module.

I appreciate your fast responses. I imagine the Cosmo, like the Gemini, will arrive with some kind of screen protector that could hold us in good stead until we figure out the actual screen dimensions. As an aside, I have a screen protector on my Gem and I've noticed that some keys have made a mark on the protector itself--I hope that doesn't continue with the Cosmo.

In my opinion, that just shows the pointlessness of a protector on a device like the Gemini or Cosmo, where the keyboard itself protects the screen when not in use.

My Gemini gets an awful lot of use, and although its screen sometimes shows faint marks from the keys, they're just grease and always wipe off completely leaving no trace.

A screen protector, on the other hand, isn't as hard or smooth. If the marks become permanent, then the protector is making the screen worse, not better!

Interesting. I carry my Gem in the front pocket of my jeans, which puts considerable pressure on the machine when I crouch. I think that's when the keyboard against the screen generates the marks.

How do you carry your Gem?

I think it will, by design.

On both devices, when the lid closes, the screen presses down all the keys (that's why the magnets are needed), which allows the devices to be a tad thinner, by an amount approximately equal to the key travel. It also allows finger grease to transfer from the keyboard to the screen or protector. While it is physically impossible for (relatively) soft plastic key caps to scratch glass, they could perhaps scratch a screen protector, though I would think that such marks mainly consists of finger grease that has hardened over time.

Today, I cleaned the glass (no protector, I took it off months ago) on my Gemini with a micro fiber cloth. The swirly touchscreen finger marks came off first, leaving a square key cap pattern, which eventually came off too. I'd guess the reason that the keyboard marks are harder to remove, is because the touchscreen finger grease gets smeared around all the time, while grease rubbing off onto the edges of the key caps get more time to oxidize. Though I have no chemistry degree to back that theory up, I do notice how hard it can be to clean old finger grease away from a well used keyboard, compared to, say, wiping a fresh fingerprint away from my glasses, so it appears finger grease does chemically harden with time.

I would thus think that hard-to-remove keyboard marks on the screen or protector can mostly be avoided by cleaning it fairly often. On the other hand, would there be a grain of something hard enough on the cleaning cloth, THAT could leave permanent marks, so I'd say it's imperative to use a really clean cloth. As, according to the Planet Computers web site, the width and height of the Gemini and Cosmo are identical down to a tenth of a millimeter, that should apply to the screen cover glass too, so whatever screen protector fits the Gemini, should fit the Cosmo too. As far as I am aware, the Cosmo is reusing exactly the same model of screen, in exactly the same, slightly off-center, location, to save a tad on the design effort.

I carry mine in a shirt pocket or shoulder bag, neither of which puts pressure on the lid, but finger grease still transfers from the keys to the screen, which isn't surprising, as they are designed to be in full contact when the lid is closed.

My Cosmo arrived a few days ago, and I intend to buy the same screen protector I have on my Gemini. As others have noted, the clamshell design means the screen doesn't need protection.

The selling point for me is that I found a screen protector which de-polarizes the screen. I have polarized sunglasses, and without this add-on, the screen is only visible when in portrait orientation. Hardly ideal for using it outdoors.

I bought the "upscreen Reflection Shield Matte Screen Protector for Planet Computers" from Amazon.

Using a matte screen protector here with the Gemini to avoid reflections in sunlight. Well, protecting the screen is not the only use of a screen protector.

Those are both perfectly good reasons for a screen protector! (I just wanted to make sure people weren't using them only out of habit or ignorance...)

I've not had problems with reflections, and my shades don't appear to be Polaroid. But I wasn't aware that polarisation-rotating screen protectors are available, so that's well worth knowing.

Yes, Cosmo has a screen protector. Key prints on Gemini even without a protector, though they do clean off. Can't see any key prints on Cosmo yet.
