under discussion as NOT being about using personal ARM devices, but about deploying devices for use in the corporate world. In that situation the ARM devices don't even come near to cutting the mustard as for a corporate usage and deployment you need to be able to easily connect to the corporate domain or there's not advantage in using the damn things at all.

Once you accept that point, then the Win 8 Pro is the only choice.

Once you get there, it then becomes a case of if you want a limited usage tablet or a wider usage ultrabook. For most corporate usages I see a touch screen ultrabook would be the better option. For limited usage such as logistics use for delivery drivers, then the surface or any tablet with Win 8 Pro would be suitable, if you insist on using Win 8.
