I have been drooling for over a year about this device, and am nearly dehydrated so I'm thinking about seriously buying this thing now. I do have a couple questions though. 1. How essential is a screen protector. I understand that the screen is infact plastic and not glass (big bummer but I guess I could live with taht). Does it scratch easily? My use is for academics and some art (pharmacy school) 2. The case etchings. In the palm rests, do they accumulate gunk? My hands are rather sweaty, and gunk accumulates on my palm rests and mouse. I constnatly clean off my device and keep my hands clean (maybe too much sometimes), and would cleaning the palm rests on these be tediuous because of the etches or did hp clear coat the stuff? Thanks!
