What exactly does "pro" mean today? I've been thinking about this a lot over the last few months, with the long speculation on what a new Mac Pro would be, and now with the MBP haswell wait. I'm not sure that apple's definition of "pro" is what a lot of other people (ie. many of the users here) think that "pro" means. Look at the rMBP and the new Mac Pro. These machines are both for the most part user un-serviceable. You can upgrade the ram on the new Mac Pro but it doesn't have a ton of room for expansion. On the rMBP, only the 15" has the option for 16gb ram or a quad core processor, and even then a dGPU may be going the way of the dodo, just in general when we consider the Mac lineup. For some, "pro" means a 17" screen. Whoops, that's gone. The story posted recently with an external GPU connected via thunderbolt may be one path forward here. But essentially, the distinction between the "pro" and "regular" computers are getting smaller and smaller. What makes a "pro" computer "pro"? And a "pro" user a "pro" user? Discuss.
