Have I missed anything? I know the old retina lags a lot, but was that fixed by Maverick?

No, you missed nothing, although they're both USB 3.0.

Mavericks did improve lag. There's not really any difference on that issue between the models.

Are you sure about the USB 3 thing? I know it's old model so I can't find the spec on Apple.com but did they just add the USB 3.0 during the secret early 2013 refresh? I don't think it was in the 2012 product launch!

Positive. I'm on a 2012 rMBP right now and just re-checked it in System Profiler.

Take the late 2013. You will not feel benefits of a slightly better graphics card in your daily usage (unless you are a heavy gamer of course), but you will notice much better speed of the ePCI SSD. Plus the new ac wifi can become useful one day (think about super fast wireless backups).

I'd go for the 2012 version actually. SATA3 ssd is already really fast. The 650M (same clocks as the 750M) has 1 gb of GDDR5 all to itself. The Iris Pro has to use 1GB of system ram instead, eating into your already limited 8gb of ram. Not to mention, the 650M is a huge increase from the Iris Pro.

The only downside is no wifi AC, which is really only an issue if you actually have an AC router.

Fair points. Correct me if I'm wrong but I believe under Mavericks the Iris Pro will only allocate as much memory as it needs, so not the full 1 GB most of the time.
