I'm trying to hold out until the next game I buy makes it imperative to buy a new computer, damn it. - Victor Ganata

I'm seeing a lot of movement to proprietary ports (thunderbolt is nominally open, but I'll believe it when there are ports on Dell computers), and continuing refusal to support standard features, like memory card readers. Also, with increasing issues related to control who gets to develop software for the platform, I am not buying another Mac. - DJF

Yeah, it remains to be seen whether Thunderbolt is going to be like Firewire—best-of-breed, superior to all other interfaces, with an open standard, but almost no one else supports it. I'm OK with lack of standard hardware features as long as they don't actually preclude 3rd party devices. But if they ever make OS X so that you can only install from the app store, I'd bail, though. - Victor Ganata

I'm not thrilled by the fact you need to buy a separate Gigabit Ethernet-to-Thunderbolt adapter, but I guess most people use wifi anyway - Victor Ganata from iPhone

All profit is in the adapter :-) - Todd Hoff

Better rationale: Your 2008 plastic Macbook can't be upgraded to Mountain Lion. - Kevin (aka ThreadKilla)

That's OK, I only just upgraded to Lion last month :D - Victor Ganata

10.1 was a mountain lion. - Eivind

Isn't the battery on the Macs unreplaceable? - Piaw Na

The plastic 2008 MacBook has a replaceable one (this isn't one of those unibody aluminum ones) - Victor Ganata

Ah well, I fixed it by resetting the SMC. I guess I'm going to hold off on getting one of those Retina Display MBPs after all. Or find another excuse…. - Victor Ganata
