Just remember, many of the same ones who are waiting now in these threads will be creating new ones soon after the release to proclaim what an utter and dismal failure the update is... while you will be happily using your computer
If you're referring to my previous argument that's not the case. I have a 2.53ghz 15" with 512mb 9600. I got it when the unibody first came out. And I was/am very happy with it. The only thing is... that was almost TWO YEARS ago. And they are STILL selling basically the same thing. So when they update I would be more than happy with what I would get. It's the fact that what I would buy now, is almost exactly the same as what I got when I bought mine in 2008.
I'm in a lucky situation though. An unfixable screen flicker has caused Apple to offer me a replacement. My current replacement would be a 2.8ghz which is still a nice free upgrade. But since it's a flicker I can temporarily live with, I'm willing to hold out for the update to maximize my free upgrade (really want the GPU upgrade). But my stance would be the same if I had a backup computer and wasn't absolutely in need of a new one.
