I appreciate the suggestion but I very much remain dubious they will get it "right". While I don't have anything against those features they are superfluous. Someone needs to get drawing and note taking right. It should work very much like writing on a paper note pad and be very easy to use. Every pen implementation I've seen so far gets carried away with handwriting recognition and other theoretically nifty features (which rarely work very well) but don't make just writing/drawing easy which is the bit that actually matters. It's more important that *I* be able to write and recognize what I wrote than the computer. I remain hopeful but so far every attempt I've seen has fallen badly short.
In fact, the note series does let you just scribble or doodle or whatever. The handwriting and formulae recognition is a feature you need to tap to activate.
