Thanks for your thoughts Maxwell, glad to hear yours is holding up well!
Curious what other designers out there are doing since the rMBP hasn't been updated in a while (approaching 500 days).
Is your machine still holding up well? Have you made any upgrades to your MBP while you wait for a refresh?
I would love an update (seems bound to happen in October), but my rMBP has been holding up extremely well (and without any upgrades). Certainly if you're in the market for something new waiting makes sense, but current model works really-really well for being "old".
