with the Surface Pro: I can work my spread sheet, type a report, then print it for my presentation at work. Work makes me $157/hr. that's a salary of $400,000.
Tablets: can't do anything productive but I can sure use wifi for internet surfing, play cut the rope, download pics, play angry bird, play more angry bird, more angry bird, then I get angry for not being on angry bird. end result: saved $1260 but can't do work (not making the $400,000 year)
with my surface pro, I can hook it up to the internet (don't have to have a wifi), look up for massages, call those masseur girls over. While waiting for the massage girls, I flip it to a tablet, play some angry bird and download some porn. When the masseur girls finally arrived at my home, I finally got my massage and the happy ending. And I am still $398,000 richer than if I had a pure tablet alone.
