I am extremely tempted to do this, but I also benefit from simple positive features like contact syncing, notes, grocery list syncing, calendar syncing, and a few other utilities.
I've decided to try one of those micro-smartphones, hoping the small screen will be fine for calendars but miserable for email & web surfing.
Sometimes I think what I really need is WiFi but no data. Sync on the nightstand, but no data connectivity out and about.
