Having the freedom to run pretty much any Windows software is wonderful, even on an 8" screen.
There are so many simple everyday tasks which we take for granted under Windows & other desktop operating systems, but are impossible with Android. Most hardware is more than capable, it is just the lack of software & some annoying restrictions imposed by Google.
Want to extract some audio CDs? Bad luck, Android doesn't support optical drives.
How about batch re-tagging some files already on your MP3 player? Android now blocks you from modifying files on memory cards & external drives, and the tagging software is so primitive you'll probably have to do every file manually.
I was very anti-tablet until I used a full Windows tablet. They were fine for reading e-books, watching videos and playing certain types of games, but for any 'real' computing tasks they were unusable.
