Software is the real problem
Even ignoring the ridiculous price, weight, and poor batteries of these things, the software is just horrible. I'd rather have my whole body waxed than have to use Windows 8's Metrosexual UI. And the desktop doesn't lend itself well to touch. So anywhich way you look at it, the experience is substandard compared to ordinary laptops (including Chromebooks) and competing Android/Apple tablets.
