Hi
Although I read a lot from the Kindle, I still pick up a hardcopy book (from my home bookshelf) and read. I don't have any specific preference, but with the kindle, you can carry 'books' outdoor with just one gadget.
I have written many pros, so here's the cons:
1. Let's say I have spent hours reading a novel. Now, I want to access the Internet to view some online color pictures or watch you tube videos. Obviously, I can't because Kindle is non-LCD/LED and in b & w.
2. I wish (sometimes) it is touchscreen. On more than one occasion, I handed the kindle to a first-time user and the first thing he did was to swap the screen with his fingers. That said, if it is touchscreen, it would probably be backlit LED, which would eliminate the non-glossy advantage
3. When you download many many books, the system seems to slow down a little.
Anyway, despite what I have written above, I am still a KINDLE lover, diehard actually.
