Not to mention the fact the you're only getting a 512mb chip, and not a 1gb chip, which means you'll probably only be able to put in 1gb later, for a total of 1.5. If you got the gb now, you'd be able to buy a 1gb chip later, for a total of 2gb. Ram is pretty important when you're working on audio. And, just because you're only djing on that machine, doesn't mean you're not going to want to use it for prod later.
the first part of that applies at most places...but not apple. apple ram is simply more expensive. always. for example. i downgraded my ram to 512 and bought 2 q gb sticks on the cheap and came out spending 40 bucks on 2gb.
i will agree that you should have bought it wil a 1gb stick, but apple doesnt solder one chip on with the macbooks, so no irreversible harm has been done.
seriously though, i suggest at least 1 GB. OS X can run on less, but it doenst make sense to run with less when performance is considered.
and one last thing, i've found that running any app that requires rosetta while i run live causes pos and clicks. might just be me...but i thought that was worth knowing.
