I haven't upgraded from my K2 yet. There's even been a K3 in my house for over 3 months and after playing with it extensively... it didn't tempt me to upgrade (even though the K3 screen is much nicer). The K3 is a little too small to be comfortable in my hand, so I know the latest hobbit Kindles aren't going to work for me either.
If it ain't broke... don't fix it.
