- Touch screen is too sensitive to be usable. When I touch the screen once, the tablet almost always take it as double taps. When I use on-screen keyboard to type, it ends up like this: "...aalwayyss ggoooodd...". Therefore, it was impossible to write this article on this tablet. See the youtube below for how erratic it is.
- In duplicate mode, Miracast cannot cast higher than 800x600 (update: Dell has fixed this problem on 12/02/2013). I tried it with Actiontec Screen Beam and Netgear Push2TV PTV3000. A Windows 8.1 tablet with Miracast is by far the best way for online TV watching,
but this tablet cannot be the one.
- No way to charge it while USB is being used. Lacking of HDMI port, this problem puts salt on the cut if you're thinking of a USB-VGA adapter.
The too-sensitive problem is not just my case, see this review:

If above three problems can be solved, this is really a fantastic tablet - thin and light. Now I hold my breath on the Lenovo MIIX 2. It is even thinner and lighter, hopefully it will arrive in stores soon and won't have such major problems.
