I first owned a Kindle and found it rather limited, both in terms of comparative price choice in the Amazon store and a few other things. I am a grad student, so I get a lot of .pdf files to read and I found that the .pdf reader on Kindle was pretty poor and choppy. I also happen to be one of the few people who is a fan of a backlit screen because I can take it just about anywhere. I did find the Kindle to be an easier device to transport, but I wouldn’t go back to it. Instead I got an Asus Transformer which does the job just fine and now I have access to many more stores for books, articles, comics, etc.
