Ah, thanks, Filark. I think I'll probably get the 10", then.
BTW, my eDGe will be a year old in two weeks -- got it on 9/15/11 and still working like a charm. I got in on the Woot deal that was posted here at Mobileread and sold out in an hour or two.
I actually use it way more than my Nook or iPod...so versatile, but without this forum I'd have been so lost LOL.
