I got mine this morning and I'm in love. Can't really compare it to anything else as it's my first e-reader, though.
If anyone is looking for a case to tide them over until official cases are released, you should be able to hack a case built for a Sony PRS300 size e-reader. I picked up a $10 case at Walmart today, pulled out a plastic spine on the inside, attached 4 pieces of velcro to the case and back of the kindle, and boom, workable case. So far my sister has accidentally spilled something on the case and my cat's tried to sit on it 3 times, and it's holding up fine.
....I'll turn the thread back over to the more experienced users now
