As an IT professional and confirmed googlite, my term, and a recently minted HAM licensee, I can tell you android tablet's, smartphones, and chromebook are all about OS lite.
They're not nearly as powerful as full fledged operating systems, iOS, Wintel, and Lintel.
iOS is UNIX under the covers on some powerful hardware. You pay licensing for Wintel, and you can get Lintel with no licensing.
My suggestion is go with one of the nixes, iOS or Lintel, depending on your budget. If the programs aren't out there for anything you want to do, you can contribute back to the community, the way computing should be.
Droids are convenient form factors designed for specific tasks, device drivers are minimally supported, much like Wintel without the convenience. Convenient yes, powerful and flexible, no.
Yes, I admit to a certain bias against M$ and I'll gladly give my PayPal account to anyone who would like to contribute to my favorite charity, me. :lol:
Bottom line, yes droids are convenient form factors for listening to music, browsing the web, gmail, google maps, etc., but that's about it.
