So far I've had a pretty frustrating experience with the Kindle (Kindle 4 no keyboard, no touchscreen) from the get-go. Sure, the box was nice, but as soon as I powered it on it was frustrating.
Since the Kindle was a gift, I had to enter in my Amazon account information before I could do anything else. Total buzzkill. I wanted to flip through a book and see what the screen was like and how it worked, but instead I have to laboriously type in my 35-character password like I'm using an NES controller.
After that, there's no sample books on there- you'd think they could put a public domain book on there for free. Every MP3 player I've ever bought comes with a few sample songs. Ok, fine. Now I have to hook it up to my computer via USB. Put an epub file on there. It doesn't support epub? Ok, fine. Put an RTF file on there. That doesn't work. Ok, fine.
Finally put a .txt file on there of a book I'm halfway through the paper version of. Apparently the Kindle has a weird concept of pages for txt documents, so I have to hit the "Next Page" button 97 times, or guess what "location" I'm at (1456 out of 4452 I guess?) and enter that in.
All of that frustration, in the first 30 minutes, just to get an idea of what it is like to read on it and page through a book. Never had that kind of experience with an Apple product. "Unboxing" experiences with Apple products have become a religious experience for a reason. Amazon is still far short of that.
