I will buy a MPB w/ Merom when its released but I'm expecting it much later than the Intel announcement. I'd say it will be a similar time to the release of Leopard. So until that day I will play with my MacBook.
I played with now briefly at the London apple store. Looks a little odd - much better tho than pictures. I think it feels good but will take a while to get used to it as if does feel different.
< 7days until I have my Macbook
As Arch said, I bought the Mac for OSX not Windows.
UNIX is superior and my favourite OS. I dont know if I'll even do a native Windows install, probably wont, may just run it in virtualisation.
Why use Windows when you can have OSX?
