Oh brother. Lay off the 'pro' ********, or make it actually MEAN something. I use my computer for my job. I earn very good money working as an embedded-systems programmer. Every machine in Apple's line-up could be considered a 'pro' machine, in one way or another. Find me another computer, desktop or laptop, that has an IO connector with as much raw speed as the thunderbolt connectors that just about every one of Apple's machines have now.
What is it about your laptop that isn't "pro" or "leet" enough for you? You can't plug in an ethernet jack? Buy a thunderbolt display and there you go. Problem solved. It's expensive, but we're talking "pro" here, right? Spend money to make money? You can't plug in an ethernet jack on the road? Take an adapter with you. You're already carrying that $2000 laptop in a case - it's probably got some pockets. And you'll be a lot happier carrying around a 4lb computer on the road than you will carrying today's 5.6lb MBP - your back will thank you when you hit your 40s.
OTOH, if you DON'T need or want an ODD or ethernet port, why not get yourself an Air? The entire purpose of having two lines is to meet the needs of two fundamentally different types of users, not to simply make one line more expensive with zero practical differences.
The PRO designation does MEAN something - at least for those of us who actually USE the features the Pro line has which the Air line does NOT have. If I did not need the features of a PRo, i WOULD have a MacBook instead, and be looking at upgrading to an Air with the next release. Maybe the Pro line has no meaning for you. So what? You are not the center of the universe. Nor am I. But then, I am not the one insisting that my needs be dismissed because they are more demanding than yours, or aren't in the majority.
Apple should be looking for a total line that will meet both of our needs. I NEED wired networking for the higher data transfer rates. I NEED an ODD to give quick run-off copies of demo videos to my clients when I am on the road. I do NOT need the hassle of having to dig adapters and externals out of my bag and plug them in (thus significantly increasing my footprint) while my clients are waiting for me to proceed with my presentation. It is FAR more impressive to just whip out my MBP, run my demo, and if the initial presentation is positively received, burn a quick copy to DVD for them to present to their board for final approval.
One other thing: I can guarantee you the weight difference between a MBP with ODD and ethernet, and an MBP w/o, is not going to be 1.6 lbs. An internal ODD weighs less than 4 oz., and the 1/8" difference in thickness the lower case assembly would need to accommodate the ODD and a gigabit ethernet port is not going to add 21 extra oz. either. The TOTAL difference in weight between a design with ODD and ethernet, and a design without - all other factors except case thickness being equal - would probably turn out to be less than 6 oz.
Conversely, carrying an ODD in external form will add more weight to be handled by my 52 year old back than a built in ODD will. So, NO, I will NOT be thanking anyone for a lighter Mac that just forces me to carry a bunch of heavier add-ons that were once built in.
For someone who used to lug around PowerBook G3 with associated accouterments before they managed to put it all in one nice package, 6 extra ounces is nothing. OTOH, being forced to go back to the days when I had to carry multiple items to do what I need to do is a giant step backwards, no matter what the rest of the design can do. I was very happy with my first PowerBook G4, that allowed me to get rid of all the extra accouterments. I will not be a happy Mac user if I end up back where I was in the days of the G3.
And a quick question: how the heck will adding a thunderbolt display to my MBP help with my need for an ethernet port on a Mac PORTABLE? Am I supposed to haul around the thunderbolt display along with the external ODD? I thought you were concerned about my aging back?
