I am new to Macs, as my 13" rMBP is my first one, so I have a question: is there a time in the past where Apple has released a new MBP that was actually lower-performing than the previous generation? Maybe I have too much trust in them, but I would assume that whoever was in charge of the MBP would be against a step back in performance. Surely they have higher standards than that. Surely whatever flavor of Haswell that goes into the new MBP will be a step up in performance from the previous generation. Surely...
The change from Power to x86 took real world performance a set back
====================
The MBP IMHO isn't really pro to begin with. Single Drive, low RAM ceiling, no Quadro/FP or even decent non Pro graphics. Pro is a marketing term to differentiate nothing more.
