True. Unless they could find way to put the software in the tablet port and the phone just authenticates so you do not have to say log into you windows sign in every time. Basically the phone holds the android software the tablet portion hold both android and windows (which we know is capable because asus have a tablet that dual boots windows and android) and when you connect the phone to the tablet and dock you have the option to dual boot into windows 8.
I suppose another direction is why stop at the phone? A USB stick with all the hardware (sans display, obviously) like the one posted earlier could be the future. Think padfone tablet concept only shrunk to down to the smartphone, where you slide out some sort of module (the "guts") to transform some other device and leaving you with basically a feature phone.
Very good point and we are not that far from that concept I think. Apple with the mini has brought their os down to a small box.
Chrome is down to a usb stick. Yeah if we could get windows down to a usb stick or if chrome os could evolve to an os that could provide the power of say mountain lion (mac pro software) or windows 8 it could change how we do business. If I could say plug in my windows 8 usb port in to my transformer (or other android tablet) and run Windows that would be worth it. But yeah the other issue would be whether or not the tablet could handle a windows 8 or a mountain lion. Actually we could probably throw apple out of this conversation because I do not see them wanting to play ball with the idea of a device running apple software that wasn't made by apple.
Then, for the most part, upgrades (for your phone, tablet AND computer) involve mainly getting a new, compatible cartridge. Like I said, I think the 15nm tech will be the key, not just because of reduced power consumption but heat generation might be very manageable (at least with some tiny fans and vents).
Also I run windows 7 on a 2006 HP laptop with 2gig RAM with no issues.
