I think you're correct there, although it's very aggravating, regardless of who's fault it is.
I still have a late 2011 17 inch MBP equipped with quad core i7 and upgraded to 16GB RAM plus a 1TB SSD. I still use it fairly regularly, in particular for Ableton Live. It's really the last MBP you could plug enough peripherals into without needing a separate hub and, key point, still has Firewire, which I need for my audio interface (USB always sucked for this because it chews CPU, whereas Firewire doesn't).
Honestly, as a machine to tote around all the time, I prefer the 15 inch form factor, but the 17-incher is great for working with a lot of tracks simultaneously, and it has all those wonderful ports:
- 3 or 4 USB ports
- 1 Firewire port
- 1 Mini display/Thunderbolt port (two would be nice, but I'll live)
- Line out AND line in (something sadly missing from newer models)
- Digital audio out and (I believe) in (using same ports as line out/in)
For the use cases I needed and still need it's a much more useful system than the current line-up. And, of course, OSX has much more capable audio handling built in than Windows (no messing around with ASIO, no app exclusivity over access to audio hardware).
