Broadly speaking I don't like a the idea of a tablet with a stylus as it would be better for a small number of use cases but worse for a far larger number.

The screen doesn't handle detail brilliantly for handwriting but uPad gets round this by giving you a larger writing area which it then shrinks onto the actual document. Basically you write an inch high and it crunches it down to about 40% of that. It works pretty well, though I'd still use the keyboard for significant text input - it's completely workable once you get used to it.
