The iPad was absolutely no choice. Quality is good, but no USB (excluding extra-photo-kit that not always funtioniert), less memory, no microSD slot, and expensive.
In the price range up to 330 euro no other tablet on the quality of Acer is approaching. Did the tablet for a few days, and I am completely uerberzeugt!
If something is to be exposed, it is the somewhat brief Aufladkabel. That's it. Otherwise, the tablet is perfect for my needs.
