With the larger price tag than most people were expecting, I did briefly go look at Windows machines as a possibility. I don't use Mac specific software, just prefer the OS and machines. So had to have a look to justify it.
I looked at a Dell XPS, really didn't like it within about 5 seconds. Didn't like the grippyness of the surface, awful feeling trackpad, and the build quality (Nearly all Windows laptops I look at, if you push down on G and H keys, the whole thing flexes... Just don't like it). So that was a no go.
Otherwise there wasn't really a lot of choice, I've disliked HP for a long time (Old prejudice), but couldn't see anything in-stores that would change my mind. Lenovo no way.
So it kind of only left the Surfacebook. Which I do think is a very interesting computer and I hope Microsoft continue to develop it, I've seen them too often recently make something interesting and then ditch it a few generations later. In its current form, it wasn't suitable for my needs sadly. I still don't like the keyboard section, although better than a tablet, it still feels like an accessory and not part of the device. And also the machine is lower power than the MBP. The tablet is vaguely useful but in reality I don't think I'd use it that much. And then finally it was the same price as the MBP... So that kind of settled that one!
I'm not against Windows computers in any way and I hope they continue to evolve, specifically MS branded machines. But this generation I couldn't find anything better for my needs than the MBP.
I've heard many good things about the Razor computers, but I still feel they target the gaming market with all those lights and tacky stuff. And for me the computer is a work thing and I want it optimised for that, not gaming.
