Hi,
Here's some computers that might help you streamlining your therapy sessions. These modern systems support handwriting, and support a high screen resolution to keep your overview within Clinical Notes. They are also very mobile so you can drag them around your therapy room while taking notes. Please update if anyone has more suggestions.
