it seems that all keys are slightly depressed after the magnet snap-closes the lid.
Four years into this thread, I'd like to go a little OT and add that yes, the keys are, by design, depressed when the lid snaps shut, to make the closed device a little thinner. Looking straight from the side, we can see that the key caps are slightly raised above the rim of the keyboard.
My calipers says 1.3mm, so I'd guess Planet, being British, aimed for 0.05". As the lid has almost no raised edge, it will, when closing, press down the keys about that much.
On a further tangent (which might be a pun in Swedish, where "tangent", beyond its English meaning, also means "a keyboard key"), as the Escape key can wake up or reboot a Planet device, this design requires some finesse. If I slowly close the lid (of my Cosmo - I didn't bother to power up my Gemini) while looking at the screen, it turns off when the front gap is about 7/8", probably just before the screen begins pressing the topmost keys. To wake it back up, I need to lift the front of the lid about 1½". This hysteresis should stop the device from oscillating between sleeping and awake (which I think could crash Android, the launcher and/or the baseband, neither of which was likely designed to handle such stress).
More on topic, I think the main purpose of the film is to keep the screen clean and a bit more protected during manufacturing, testing and shipping. On my Gemini I left it on until, after some months, it came loose in a corner. By that time, it was full of keyboard-shaped finger grease imprints and little scratches I couldn't wipe away. After removing it, the screen looked like new and, while still attracting finger grease, was easier to clean and less prone to keyboard marks. As it is both harder and smoother, my fingertips clings a tad more to the glass than the somewhat silky plastic, which, on the other hand, feels slightly more slippery to my fingernails or my capacitive pen (an Adonit Dash 3).
On my Cosmo, over two years in, the film is still there. Just like my on Gemini, it has tiny specks of authentic factory dust™ trapped behind id, and the film a bit worn now, but hasn't, so far, begun peeling and I haven't been sufficiently bothered, to remove it.
