There goes your battery life though when you put the dedicated gpu in it running at a higher resolution.
And if it was as easy as just popping in a gpu inside the chassis in a minute then I'm sure they would offer a dedicated gpu option. I don't think it is that easy. Probably requires a different internal design. Another assembly line at the factory maybe? Another model for retail to stock and learn about?
All for what? The few gamers that want to buy 13" mbps for $1500 to play Windows games who just refuse to step up to the 15" MBP?
Ditch the optical drive. Plenty of space wasted by a device few people use every day. Then we could get a better cooling solution and larger battery as well. Problem solved!
