Switching between users can be a bit too complicated for older users. Pairing with Bluetooth even more.
Otherwise seems like a good device. Not so sure about the software. iPad software is missing printing support.
The product has a good support by a German company. And that's a plus. Too bad my parents do not speak German, and I have to be instructed to use the device. I figured it's better if I explain the basic usage (forget the Bluetooth pairing, it seems annoying) and eventually can I synchronize data.
