Evan has an old MacBook Pro running Boot Camp for Windows 7. He uses it for 3D modeling software and gaming. It's getting long in the tooth and now he's looking to upgrade. Leo says that Evan may want to wait for Intel's new Skylake processor. It may not be that much faster than the current Broadwell line, but it'll future proof him better. If he can't wait, Broadwell will be fine.
Evan is wondering if Apple will ever release a larger 17" screen again. Leo says no. Apple's pretty committed to the smaller form factor and wants users to connect via a larger desktop monitor. But the screens have improved in resolution, and a 15" Retina MacBook Pro will have better resolution and color than that older 17" model. A higher end 17" Windows machine is his other option, but he can't run OS X on Windows. Dell still makes a 17", as does Asus with its RoG line. But he'll be giving up OS X, which may not be the end of the world. Leo suggests sticking with the 15" MacBook Pro with Retina though. It's very nice.
