Check out Evernote - Syncs to cloud for access via PC/Mac, smart phone... and I haven't had to check into the various Pad OSs yet.
Easy to use, whopping $45/year for unlimited use (up to 60Megs per month is free - would be useful for testing)
Setup a doc with your own layout, fill in data at the appointment, embed picks in the form or 'notebook' and it's done.
Time for another appointment? Sync the Masterform to the next 'client', visit and fill it in, same deal with the pics...
Hope that helps.
