What do you do if your home turf of PC sales is being eroded by tablets? If your answer is "sell tablets as desktops," then you're on Meg Whitman's wavelength. At an event in Beijing, HP announced a 21.5-inch, Android-powered tablet that's expressly designed as a desktop unit. The HP Slate 21 AIO comes with a full-HD touchscreen and NVIDIA's Tegra 4 internals, running Android 4.2.2. Prospective owners won't need to purchase an artists' easel, however, as there's a handy rear kickstand that'll let you stand it upright or at a 30-ish degree angle (pictured after the break), making us hope that its digitizer is sensitive enough for pen-based drawing. There's no word on pricing or availability, but there's a press release, translated from Chinese, after the break, if you'd like to know more.
