So your argument is that the dual core i7 13" Surfacebook is £500 cheaper than the 15" quad core MBP, interesting comparison. Better be quick Microsoft is throwing in a free xbox one as well to encourage salesTotally agree, it's simply based on what value you assign OS X. Imo it's not worth the £500+ difference between a maxed out Surface book and a mid-level 15 inch rMBP for me. Windows annoys the **** out of me but the value for money is ridiculously higher on windows machines
