There have been some speed bumps along the way.

Paint coating--The new batches claim to have it corrected. Time will tell

USB 2.0 connectivity to some systems? (Connecting to USB 1.1 seems solid)
Battery charge life ... Seems to be hit or miss. I get lots of pages over a week.
It is a new model and we were early adopters
There are things I wish that were better, but if nothing got fixed, I could live with what I got

as I have work arounds for most issues.
Give it another month for the Paint to dry
