In term of specifications, most tablet pc models come with the minimum of 12" screens and 40gb hard disks. So your requirements pretty much encompasses every tablet pc out there. What you might want to consider beforehand are the following: 1. Convertible (with keyboard) or slate (external keyboard). I personally use a convertible model, since my typing is still waay faster than scribbling. 2. Connectivity. Do you need bluetooth built in ? 802.11G or B? 3. Battery life. Depending on how many power points there are in your lecture theatre, this is likely a big concern if you plan to take lecture notes. 4. Processor power. Tablet PCs range from 800mhz to 1.6mhz. if you plan on running hefty simulations,etc., you might want a rethink. Finally, ask yourself if you -really- need a tablet pc. Remember that you are paying a premium for being able to scribble on your laptop, at the same time forfeiting some screen quality and performance.
