I'm using a Fujitsu tablet pc and have been writing notes in amazing charts for quite awhile, while I'm talking to clients, I'm a psychiatrist. It "tries" to make a word out of what I write, usually it is spot on, at other times it makes up some bizzare word I've never seen before, at other times it makes up a word, not the right word. Sometimes it picks the right word but then when I touch the insert button it changes the word from what was displayed in the box to something that might look like it in the text. Very frustrating. It doesn't check grammar or syntax and if the word is a word the spell checker in Amazing charts will assume it is just fine as long as it is spelled correctly, also frustrating.... So I have to proof the note before I save it to the file. I thought about writing the notes in Word, but that is more work. If Amazing charts had a first class spell checker/grammar verifier/punctuation master in it, it would be great. I've ended up with some bad notes when I didn't take the time to proof it before I saved it. I do love the technology. It's fantastic in word or in One Note. I've never used a circle technique. The pen will only do letter recognition in AC to the best of my limited knowledge.
