The MacBook Pro I would want is the faster 15", which comes with a reasonable 1GB of VRAM. This machine costs $2,200. To equip a $2,000 laptop with 512MB of VRAM is sheer nonsense. Anyway, to get a similarly spec'd PC laptop, I could buy something like an Asus N56VZ for around $1,200. There are both fancier and more frills-free laptops with similar specs, but the premium for the Mac hovers around $1,100 to $800.

Don't try this with someone who doesn't "have" to be nice to you because you're in their store.
