Last week we took the iPad Pro again for a spin, trying to verify, or refute, Apple's claims about the tablet being the ultimate PC replacement. And just in time, the company just released a video ad just few days ago that tries to make the same point again. But iOS is hardly the only game in town, especially on mobile. And while Google hasn't exactly made a similar claim for Android, others have spoken for it instead. But before go off on another crazy adventure, we first have to look at the few, of course unofficial, attempts at making Android the ultimate PC replacement, as far as OS is concerned at least. Yes, this is the so-called "Android PC".
