Need advice from techy friends, please! :)

Item #1: Rachie needs a new lappy. Considering getting a high-powered desktop for video editing, gaming, etc and a netbook for everyday stuff (FB games, browsing, StumbleUpon, Netlflix, doesn't have to do anything super fancy). If you've got a suggestion on either, please share... But particularly the netbooks as I currently know little to nothing about them and CNET reviews have only screwed me in the past. And I'm not getting a Mac, so don't go there. :P (I was the outcast in college for using PCs, and I'm ok with it. You try going to film school and hating Macs. ;) I do know how to use them and have actually spent a ridiculous number of hours on them for various editing jobs. They just aren't my thing.) It was a big enough concession for me to get the iPod thats currently geeking out on me... Speaking of...

Item #2: The issue with my iPod doesn't seem to be going away. I've tried syncing, powering on/off, and defaulting to original settings so far. Haven't gone as far as wiping it yet... But maybe that's going to be my only option... It's spontaneously returning to the home screen in the middle of any application use after only a few seconds to nearly instantly. Trying to go back to the application just results in this weird cycling thing... Half screen with recent apps showing, then home screen again, then search screen, then home... Its even doing it when I'm not touching it... Right now its just off because I was getting too annoyed with it. Its an iPod Touch, bought in late 2009. I can't find a dang thing online that sounds remotely like this problem. If you've got anything, I beg of you, point me in the right direction. :)
