Mobile Devices: One Generation From Useful (Alertbox)

Nielsen says: "I've been using a T-Mobile 'Sidekick' as my combined PDA and cell phone for the past half year. The Sidekick is also known as the 'Danger Device' or the 'Hiptop.' When I saw an early Danger demo two years ago, I was excited about its potential. Now, after actually using it, I've concluded that one or two more generations of device designs are needed to achieve true usability."
