I live in Shenzhen, a city in China that is right across the border from Hong Kong, and is within 200 miles of where many of the name brand and off-brand tablets are assembled, if not made I went to a computer market today and was amazed at the number of off-brand tablets that are being sold. True, there are only about 8 different sizes and a variety of options within those sizes, but they are all staring at me as I walk by saying "buy me! buy me!" The boxes and descriptions all have high claims - dual core, 16 gb, etc but how do I know if they are real or not? Is there a small android utility that I can download and install on a tablet in a few seconds that will tell me everything that is "under the hood"? I will use this tablet mostly as an ebook reader and movie viewer, and occasionally for Skype when I travel. Is there some way that I can download Skype for Android onto a flash drive and then install it on the droid I am looking at to see if it will work? Also, I would like to take in a movie, also on a flash drive, and see what it looks and sounds like when I play it on the droid. For playing movies and Skype - I am guessing that these are the most hardware taxing things I will be doing - what kind of hardware do I need? Will Android 4 let me have more than one app open at a time? Any help? Anything else I should look for?
