Re: The problem with Android...
The problems with Android (and in some cases Linux):
Most programs are not tablet optimized. This ranges from not using all of the screen to wildly switching between protrait and landscape modes. MS shares one UI between phone and pc but programs are written for either WP8 or Win8, Android is one OS for both and the developer either has extra work (often not honored by customers money wise) or develops for the far more common phone platform
The ARM CPU is nice for mobiles and media devices but too slow for more demanding tasks. The N80x0 struggles with Handwriting Recognition and forces the user to change recognition mode between character, number and special signs among other deficits. And Speech recognition, something an Atom can do offline, needs the GMail-Man and a running Internet connection. Android/x86 would fix some of that by using more pwerful CPU but why?
A useable device is more than an OS. And the whole software infrastructure for penables under Android (and Linux) is massively lacking. HWR is around what Windows had 2003, the Journaling software is unstable (SNote) or Cloud-Only (EverNote - leagal problems for EU companies!), Speech is "online only", Drawing software is not even up to ole ArtRage2 and so on
Printing under Android is a nightmare! A 25€ "printserver" works fine for all the printers (Ink and laser) and Windows boxes (XP-8) we have. It does not for Android. That either needs "Internet" (a no go in various situations) or works only with selected printers and a special app (And strangely - the cheap ones, even WLAN ones, are not supported) or needs a full sizes CUPS system
Office under Android is not up to OO let alone MS Office. "Can basically show the Powerpoint" is often not enough
For 500€ I can get a Atom-based tablet pc with a mature, stable OS that simply works and has all the software and the seamless integration that 92+ percent of PC networks need and use
