Not surprising. The original MBA when it came out was underpowered (if memory serves) compared to other laptops at the time and now it's a powerhouse that many have as their main machine.
I fully expect the same to happen here.
I have to say Win10 looks pretty good actually. I'm certainly not going to jump ship to Windows (although I do dual-boot to Win7 for playing games and some light school work with Word) but this looks YARDS better than Sinofsky's disaster of Win8
I see a lot more MBA's than I do MBP's but the point still stands - Apple laptops (whichever one you choose) are the Gold Standard for laptop design today and one I would expect to continue with the new MacBook
