Been using mine since the first batch went out and it's a great replacement for paper, for notes.
The one thing that annoys me is the battery life (about 6 hours of more or less continuous use). So during a work day I end up having to keep it permanently connected while at my desk (easier than charging at odd times). I understand why it's not as energy cheap as just an e-ink reader, but what annoys me is that they obviously decided to sacrifice battery size to make it light. The result is that the device is almost _too_ light and thin.

I'd take twice the weight for more battery life.
