Toshiba Qosmio looks interesting.
Its a widescreen notebook, TV, PVR (can record TV programs to the Hard Disk), has good speakers and DVD writer.
This one notebook can replace your PC, Notebook, TV and Audio system.
The price is bit expensive: 17″ costs US$ 3000 (Street price around US$2000).
It runs Windows Media Center, now only if we could replace that with Linux, it would be even better 🙂
Linux runs on it but getting the TV functions to work may be problem.
