Surprisingly, the best HWR I've used was on a Tablet PC a few years ago. I am really impressed with MS' implementation (omg nooo). The Newton was definitely before my time but I remember it when I was just getting into computers. Just as I started to appreciate it, its last model 2100 came out.

Frankly, on a device the size of an iPhone (<love!>), HWR would seem a bit rough... and considering how effective their on screen keyboard is, I don't see Apple getting around to it.

I'd love a 5 or 7 inch "iTablet" with the same OS as the iPods, a meatier processor and license MS' ink tech.
