I swear. Why do people compare these things in the first place. Yes, it's under $100. No, it wont play HD games like Need For Speed. Thus why several tablets are still selling for over $300. But if you want a color screen, an e-reader, use apps for local news and weather, or check/post on Facebook, these tablets are fine. The ones that retails stores use for inventory is basically the same thing, only difference is that they're usually running Android 2.1 and has a laser on the top to scan bar codes. It has a 1.2Ghz CPU (single core?), it only has 512MB of DDR3 memory, it only has a 0.3MP camera. But it also includes a keyboard and a case.
If you want to pay a tad more ($100 - $150), you get the next step up. But those are still junk when playing Mpeg4 with more than 30fps, they still lag when playing higher end HD games, etc. But it's strong enough to send your Angry Bird across the screen with no lag.
I'm not sure when the "You get what you pay for" terms has been erased from people's minds, but it's still true. No you're not going to find a sub-$100 tablet that will perform like a $300+ tablet this year unless someone will have one on Black Friday. But yet those are the people that will stand in line or fight with people to get a $200 Celeron laptop and expect i7 performance. Not going to happen.
