I was thinking of getting a Cool-ER, but think I will hold off for the new models. I think they look fine, and I really like the idea of the compact - smaller form factor than a 5" device but with a 6" screen - now that's cool!
I hope they also work out some of the kinks from the first model firmware/function and make the new models a little less troublesome, but this may be too much to hope for - time will tell, I just hope they avoid introducing a whole range of new issues... and here's hoping they have some cases for the new readers as well...
