A less technical evaluation than @dwanthny's.
Similar speeds to what @dwanthny reported in all things.
initial display when starting CC is not instantaneous, but close.
2200 books synched in less than a minute and a half (on a Nook Color!!!)
And the features enhancements over the last few releases...
Sort and group remembered.
Connect synchronization message changed to a progress bar. Much better than the spinning circle, which was much better than nothing.
Overall and per-book progress bars during book transfer.
Reliability has gone way up, with errors almost (but not totally) nonexistent.
Even on Nook Color!
Now, what new goodies will y'all have for us tomorrow? :-)
