writes "It looks like Nokia is intent on knocking the ball out of the park with its Linux-powered Internet tablets. Today, the company unveiled the N810, its third attempt at hitting a home run with the concept. The new model adds a slide-out hardware keyboard, and also a built-in GPS receiver and FM transmitter (for in-car listening), among a number of other enhancements (such as a faster CPU and more memory). At this point, the device is positioned as an email and browsing tool, a social networking aid, a GPS, a VoIP phone, and a multimedia player (and streamer, thanks to built-in WiFi). But are the fans jumping out of their seats at this latest swing from mobile phone heavy-hitter Nokia?"
