A couple colleagues recently described for me their ideal Tablet: a slate with a 14″ display, 1200×1024 resolution, 1.5+ GHz processor, 1GB memory and 20GB+ drive. Sounds good to me.
I’ve also been wondering about super large displays. Just think what you could do with a hi-res 33″+ plasma or LCD display with a digitizer built in. I saw something similar at CES, but I’ve forgotten the company name. I’m not sure if it’s digitizer can keep up with the Tablet PC’s digitizer specs, but wouldn’t it make an interesting “Tablet PC?”
