My sole reason for buying a Kindle was the Amazon bookstore. I had my PRS-505 for almost 10 months when the Oprah coupon came out and I ordered my K1 the last day of the coupon Oct 30th!
I never use the dictionary. I really don't have a need for it and I usually turn on the wireless once a month so I could do without that too. I thought the K1 was ugly but it looked way better in person (no exaggeration) but I love the K2 (sold the K1 on Feb 9, after owning it for 3 months and 2 days to buy the K2).
