Quad Core, Thunderbolt In New MacBook Pros
Although as I write this the store is still down, the Apple web site has officially published the specs for the revised MacBook Pros, which top out at 2.2GHz quad-core Intel Core i7 for the 17" as well as offering a 512GB solid state drive. Somehow I don't think my boss will let me expense the one I want.
I thought the same before using a MacBook Pro every day for work for a year.
You just don't get the stability, performance, battery life and build quality in a cheap Windows notebook (I've bought tons of them after much research when I worked in IT). Runs for months on end, 80 hour weeks, never shutdown, rarely restarted, basically never gets in my way.
