I have Gemini for about a year and Cosmo for about a month.
Both are great devices. Have not had any issues with either device.
My Gemini looks like new.
I tend to handle all my phones and mobile computing devices very carefully.
Keep Gemini in the leather sleeve case when not in use.
Awaiting my Cosmo leather case to do the same.

My work environment involves me constantly walking around and jotting down information. I would waste an enormous amount of time putting my phone in a sleeve, unfortunately.
And the idea that you would absolutely need to use a sleeve for a phone is an indication that it's poorly designed.
I have to think that PC deliberately used plastic for the hinge to keep down costs. But they could have made the sheath for the hinge pin be thicker. Planet chose not to do that.
It's unfortunate that they decided to keep using plastic hinges on the Cosmo.
The best designed handheld PC hinge is that of the Sharp Zaurus SL-Cxx series. They were able to rotate the screen around 360 degrees and could be adjusted to any open/close angle. It's a shame that PC went with a variation of the Psion design.
The HP Jornada devices also have better hinges than the Psions or the Planet designs.
It's a shame that Planet did not try to license or imitate the Sharp or HP designs. The hinge is the most critically important failure point on a keyboard device.
