I was able to buy a Paperwhite at Best Buy this morning. I called first and was told they didn't have any despite Best Buy's website showing them in stock. I decided to drop by the store anyway; they didn't have any on the shelf, but when I asked, the guy in customer service said wait a minutes & came back with one.
I was really nervous to turn it on the first time; dreading the rainbow of colors others have on theirs. I'm happy to say mine is almost perfect! Slight shadowing at the bottom when the light is turned all the way up, but other than that so far it's great. I haven't had a chance to read more than a couple pages, but if the screen stays the way it is now, it's a keeper. I'm still trying to figure out which font is the closest to the one I'm used to on my Touch. I need to stop comparing the two and just read!
My only complaint so far is the way they've buried the wifi on/off option. A very minor issue that I'm sure I'll get used to quickly.
Thanks to the original poster for starting this thread or I'd never have known Best Buy got the Paperwhites in stock.
