I have bought two Samsung Galaxy Tabs (from different generations) for my mother and they are obviously subpar devices. Windows will minimize and close left and right; basic text editing it jumpy and therefore takes forever; clicks don't always register; the screen randomly auto-rotates; they ship with outdated versions of Android and receive no OS updates, etc. Mind you, the Samsung Galaxy Tabs are considered mid-range Android tablets so I can't imagine how awful cheaper tablets are.<p>So no, I can't imagine using Android tablets as a professional considering they work so poorly for even the most basic usage.
