So I'm sitting in a cafe, typing this on my 1.5lb, 8" laptop with the aid of a Bluetooth mouse, via the 3Mb internet connection provided - again through Bluetooth - by the phone in my pocket. I remember downloading the shareware release of Quake to my spanking new desktop's 210MB hard disk over a 33.6k modem. It took three hours. The future seems to have happened while I wasn't quite paying attention...
