I'm on the other end of the spectrum, graphics wise. IMO, if they don't include a top performing graphics chipset, it's practically a deal-breaker for me.
I *do* like to play games on my machine occasionally, and don't want them to be a sluggish embarrassment when they're run on it.
Not only that, but when one attaches a large external display, the graphics performance becomes more of an issue too, when it has to refresh that many more pixels than the native resolution of the built in 15" screen.
For far too long, Apple has neglected graphics performance as only a minor/secondary concern, and that's the area where the Windows PCs keep stomping them. There's no reason it has to be that way.
I'm fine with Apple offering CHOICES, for people who don't care about better graphics performance -- but good, dedicated GPUs need to be an option for any notebook they put a "Pro" label on.
