Well I may very well end up regretting it, but so far I like it. Now I will say the book I bought wasn't "delivered in seconds", although it wasn't too bad.
The other thing is, I went to my local B&N and looked at the Nook and that thing is a mess right now. Maybe if they get the bugs worked out, it might be superior to the Kindle, I don't know. But for me, for now, the Kindle seems fine.
