I think one possible EMR you could look at using is
MedScribbler since it is designed to use handwriting recognition. I imagine you could choose to do it recognize your handwriting or not.
As far as hardware there are a lot of good choices out there. I personally prefer the convertible tablets, because then you are flexible enough to open the keyboard and mouse if you need it. If you want a pure tablet I've heard good things about
Sahara tablets.
I have a psychiatrist doing EMR, but he types everything into it. He didn't see the need for a tablet since tablets become more useful the more mobile you become. He likes EMR quite well and espescially likes the ability to run reports on diagnosis/RX/demographic info that he can use for future research. Not to mention no more searching for charts.
