I owned a K1 from June 2008 to February 2009 (sold to make money to buy something else). I recently just got my K2.
First of all, I was COMPLETELY satisfied with the K1. I loved it, EXCEPT that the back on mine was loose and came off a lot. Not a huge deal, but it was a little irritating. The button layouts didn't bother me after I got used to them. I was just so busy with work that I didn't have time to read much, and when it got time to raise some money I went after the things I didn't use as much to sell.
HUGE MISTAKE. What a dummy. I regretted selling the K1 from the moment it left my hands at the post office. My only consolation is that I sold it JUST before the K2 came out, and sold it for $300, making most of my money back.
Fast forward to a month ago. All the noise about the Nook started to make me long for my beloved Kindle again, and as I was reading "A Christmas Carol" by Dickens on my Droid, I started thinking about how nice it would be to read it on a Kindle. So, I came on here and found out I could buy a refurbished K2 for $219!!! Whoa!
So I took some money I had been saving up for such an occasion and began researching the Nook and K2. After a LOT of reading, hands on videos, etc, I came to the conclusion that while the Nook MIGHT POSSIBLY turn out to be a good device, it could also turn out to be a giant plastic turd, and I KNOW the K2 is a solid device. Add to that the fact that I loved the K1, and it was a done deal.
I ordered the refurbished K2 for $219 (FREE shipping):

and the M-edge Touring Kindle Sleeve in my favorite color BIG ORANGE for $24.99:

With the free shipping, my K2 arrived in only 5 days. The cover arrived in 4 days.
The Kindle is manufacturer refurbished. Translation: It's brand new, not a scratch or fingerprint on it!
I opened it up and to my glee, Amazon had already connected this K2 to my account, and ALL of my previous ebooks were archived, ready to be downloaded again! Yay! 3 minutes later my collection of ebooks was now on my new Kindle.
Remembering that I was in the middle of "A Christmas Carol" on my Droid, I jumped to the Kindle store and found a free copy of it, and began reading it. I was late to get to work, so I put the K2 down and started down the road, sad that I couldn't keep reading. Then I remembered that this little beastie has a text to speech feature! I held down the bottom two outside buttons on the keyboard and the K2 picked up where I left off and read to me while I drove! BLISS!!
Bottom line: I am THRILLED to have upgraded to the K2. While I loved the K1 and had no problems with it, the K2 is most DEFINITELY a solid successor to the K1. No doubt even if I had kept the K1, I would have eventually purchased a K2. It is sleek, comfortable, and most of all, FUN! I don't care what other users think about Amazon, Barnes and Noble, Sony, whatever. I LOVE my K2 and am totally satisfied!
I hope my little epistle has helped you somewhat.
