To all who replied, thank you. This is awesome.
Thanks for outlining the difference between the two. Now I know and can ignore it. But if I didn't, I'd always be wondering.
This certainly puts my mind at ease. Well, at least with regards to [NSArray new]. Other issues shall remain uneased for the moment.
Cheers.

The class method array is much like alloc/init/autorelease in the MRC days although it may coalesce things, but that's an implementation detail you as a user shouldn't be too concerned about.
