I miss the Sidekick, myself. Was the perfect device for writing while standing. Physical keyboard and a big-ish screen, with the form of a modern smartphone.
The swivel design made finding a decent case tough though. And there were few apps.
Which was an influence on the first Android device, the HTC Dream. Swivel keyboard AND a trackball. It was pretty cool but unfortunately didn't catch on.
