Personally, I would rather have a win 8 ultrabook or detachable, and have android, chrome os etc if required running in a hyper v instance. That would require a laptop with at least 8g of ram to be comfortable.
Having said that, I have not seen an android install package that can be installed on hyper v
I like the sound of hardware capable of running these windows productivity applications getting full android support... Takes the hardware argument away from those who say Android can't replace Windows.
