Which ereader should I buy, and why?

Asked by stevenb (3836) December 16th, 2009 from iPhone

I can’t decide between the Sony ereader touch, kindle, nook, etc. I have read reviews until my eyes are bleeding. Most of what I have read give the edge to the kindle only because you can buy books over wifi. I don’t really mind hooking it up to my pc, and I already have a bunch of books on there from my older ereader that died. with the Sony you can get books at multiple places, versus only amazon for the kindle. The nook is an unknown because it is so new. Please help!!!
