There are good Laptops with that screen resolution running Windows. They might be not as pretty, but they also get the work done. And Windows 7 isn't that bad anymore for a Windows. Have to work with it too almost on a daily basis.
After all you are working with tools on a computer. And they look the same today, no matter which OS they are running on. Of course there are some things I would miss from my Macs regarding my workflows, but overall there is nothing that would by a road block in any way...
Apple really became an evil money machine... Just that makes me uncomfortable meanwhile to use their products. It seems meanwhile that you have to figure out for yourself now which platform is the lesser of two evils: Mac or Windows. And honestly, I am not sure anymore...
I spend a great deal of my spare time re-installing Windows, updating AV and AM products for buddies still using it. There are indeed cheap laptops around for the platform...It just isn't a road I'm going down...ever. I guess I'm lucky in that my MBP is pretty new, so Apple have time to sort out new stuff...I see no reason why we can't have a 17" without an optical drive bit with a large SSD. The reliability might not be there yet on bigger solid state drives, but in a year I think it will be. Lose the HDD and the optical and you lose a lot of weight....That's fine by me, my pro is a heavy machine, but I do want that 17" screen.....Hope somebody from apple is reading this rant...
