Even ipad handwriting recognition has weak points. For example, a q by itself will almost always turn into a 9. I wonder if PDAs had it right after all and we need to adapt our characters to make them more easily understood by machines.
My handwriting, because of a life of typing (this year is my 40th year of 10 finger touch typing; I was 8 when I got my certificate, so I basically skipped writing), is horrible and only I can read it. The iPad cannot, at all.
You remind me of a Windows CE PDA I had in the late 90s through early 00s [0] that had a pen stylus and consistently amazed me that it could flawlessly interpret my scrawly scribbles perfectly - I'm hard to please but it always amazed me and I felt in awe.
My experience with every hand-writing recognition facility since has been it has got worse, more opinionated, and is probably tied too tightly to grammar and spell checking - rather like what I call "destructive texting" when predictive typing on mobile devices constantly auto-replaces words after I've typed them without me noticing until a message is sent!
[0] I still have it although not powered up in a couple of years!
Out of context, a q and a 9 might be hard to distinguish; but all you need (in context) to tell them apart is where they appear vertically in the line that they're on.
