Ok, its close to decision time, and I need somme help. Do I go with a well-established tablet manufacturer, or with one of these chinese brands that I have been hearing about? Saving between $150-$200 is very appealing, but I wwant to be sure that my purchase is the right one. This is my first tablet, and I don't want to rush into something. How reliable and comparable to Samsung, Motorola, or Asus are Cube, Window and Ainol? I have been focusing on the motorola xyboard, though I wish it had a 1.5 ghz processor and memory expansion capabilities. I like the build of it and the size, but it costs $400 ... please advise. Thank you.
