I'm looking at exactly the same machine, and with Haswell not appearing and the early 2013 machines having a replaceable SSD, I'm having a hard time justifying waiting any longer.
802.11 ac would be nice, but I already have a strong n connection via a last-gen AP Extreme, and I don't need a range increase.
PCIe SSD is "better," but I'm guessing I won't notice the difference over the early 2013.
Longer battery life is always a plus, but how much is "enough"? From what I've read, the early 2013 life is at least as good as my current MBP's, and I'm on the AC adapter a lot of the time anyway.
The increase in processor power over the current 2.7GHz i7 is incremental.
There's no reason to believe the Retina display will be any different on the Haswell.
I doubt I could ever saturate a TB 1 port, let alone a TB 2 port.
As I want this machine to last at least as long as my current MBP (>5 yrs), it strikes me that the ability to upgrade to a 1TB SSD in the future is a plus over the Haswell machine.
I qualify for the Education discount, so I get the $100 App store card while the BTS promotion is on.
I can always return the early 2013 machine in 14 days.
So:
Anything I'm missing, folks, before I stop by the Store tonight?
I'm on a 2.4GHz C2D, late '08 MBP. The early 2013 scores seem more than 3x higher -- I'm hoping to see more than a mere jump.
