So I jumped the gun on a $28 NIB Tg3 Bl82 non backlight version.
It's arrived, and the first thing I tried to do is remove the keycaps to get that rubber membrane out of there, except problem. The first keycap I tried to remove pulled the rubber membrane up with it and I'd rather not damage anything at all. Anybody know what's going on with that? It does have the touchpad/rubber dome membrane.

The rubber membrane also makes the spacebar feel really strange, not sure how to explain it. It feels crunchy for some reason.
