For the record, I’ve switched to 100% e-books since moving from Denmark to the US. (Okay, I have 3 hard-cover books with me, but they’re the exception.)
For the record, I hate the Kindle and love iBooks. Kindle App for iPad sucks. The iBooks App rocks.
I’ve even re-bought books on iBooks that I’d originally purchased for the Kindle, just because the experience is so much better. I wish Amazon would hire better software designers and not just compete on selection.
