Should I assume you say this because you'd like to have it by Friday? Or did I miss speculation that updates might be introduced this Friday?
Yeah, all I'm looking for is the bump in processor, maybe memory (though I think the issue there is the proc's ability to address more memory; I think 3gig is the limit of the C2D??), and 802.11n. Nothing major, just the "best" of what is now "common" (in this case, at least the best of what's possible in a MacBook).
Unfortunately I think the Mac Mini only supports up to 2 GB memory still. Its the only Mac computer that is severely handicapped in this area. MacBooks can now go to 4 GB, as well as MBP's, and iMac's. For Mac Pro's, if you can afford it, you can opt for a whopping 32 GB of memory.
