I'm sick of seeing the posts about the Surface Book being "twice" as fast or this and that over the MBP. You want to say it's better because you can detach it from the keyboard and carry around a 1 hour battery life tablet? Fine. I'll give you that, the MBP doesn't have a tablet mode. You want to say it's better because it has a surface pen? Fine, I'll give you that, the MBP doesn't have a pen/stylus built in. You want to say it's better because it can play games better at a cheaper configuration than the MBP can? That's true. If, for some reason, you were buying these machines to play games or you needed GPU intensive tasks less than $2000, the Book is better because you cannot get a discrete card on a Mac less than $2500. However... I can't stand people saying that, price vs price, the Surface Book is faster than the MBP because it's totally and completely not. At $1300 the MBP wipes the floor with the Surface Book because a $1300 Surface Book doesn't even EXIST. And don't say "Yeah well, for only this much more, you can get this..." Because it's not like a comparable MacBook will just STAY at the $1300 configuration. The cheapest Surface Book that has a discrete graphics card isn't even $1500. It's $1700! And it only has a 128 and 8GB and i5 at that price. The worst part is, the i5 is lower TDP and slower than the 13 MBP i5. But what do you get in a MBP at that price? Pretty much whatever you want: You get the 256 SSD, 16GB of ram. You'll wipe the floor with the Surface Book in real world battery life, CPU related tasks, memory related tasks and storage related tasks. Notice none of the reviewers are testing single core CPU usage or storage speeds? They don't because the MacBook would dust the Surface book and modern tech journalism is highly influenced by advertisers and marketing. And once you touch $2000, it's not even a real comparison anymore. The 15 MacBook is better in almost every way. The quad core is literally twice as fast as the low watt dual core i7 in the Surface Book. And at $2500 for the Mac, you get a real quad core i7, 16GB of ram and 512GB of storage. $200 cheaper and it's better in every way. So in conclusion, if you want to say that the Surface Book is better because you ride on these strange airplanes that are for some reason unaccommodating to 15" MacBooks but super comfortable with a 13" Surface Book (I ride coach on Southwest and NEVER had issues with my 15" MacBook), then say that. But don't every say it's faster than a MacBook all around, because dollar for dollar, it's NOT. And it doesn't matter if it's more expensive by $100 or $500. You can NOT compare their speeds unless the price is the same. Put the $1500 Surface Book up against the $1300 MacBook and you won't be surprised at how awful the MacBook beats it. At $1700? I'm sure if you threw a 3.1 i7 in the MacBook, it would beat the Surface Book even in GPU tests (remember, the IRIS 6100 is CPU speed dependent).
