Plastic slip cover so hard to take off!

I noticed the same thing on mine, but I used the same trick that works on the NSpire (although the cover on the Prime seems even harder to remove than the NSpire!), which is to use both thumbs (one near the top and one on the curved bottom section, with other fingers underneath) when pushing the calculator out of the cover. This leaves nasty thumbprints on the screen, but that's kind of expected for a touchscreen calculator anyway!

Maybe it loosens up with use?
