I'd agree with that statement but for me, it still bothers me to pay so much money for older prior generation technology.
I'm happy Apple decided to go C2D for this. I bought mine immediately when I saw the words "C2D - nVidia". A Core i3 with an Intel X4500 would have forced me to wait for a 13" MBP.
You see older prior generation technology, I see a processor that works. My Pentium II is still chugging along, and I haven't run into any software yet that says "You absolutely need SSE3 for this to run!". Until Apple sorts out the IGPs for Core iX, C2Ds are a very good choice.
Seriously, people that "absolutely need Core iX" need to tell me what assembly instruction is required for their university course work that Intel introduced in the newer architecture.
I'm running a quad core i7 desktop and I can easily say that I don't need all that power, but it was fun building and its great when I want to run a windows VM, a ubuntu VM, and have Aperture up and running.
Just last weekend I was working on my website while doing some patches for work systems. I hooked up my Windows VM to the VPN at work so it wouldn't destroy my home net access (the work VPN blocks out a lot of traffic to certain websites) so Outlook, Internet Explorer, 3 dozen putty windows, had Illustrator CS5 up and running as I was doing my site logo, had my Slackware VM running, about 5 terminal windows, iTunes for the background noise and the machine was barely sweating. That's not even counting all the other crap that is just running in the background like MSN, Skype and Transmission at all times. This isn't some quad core beast, just my Macbook 2.0 ghz with 4 GB of RAM. It used to do the same with 2 GB but 2 VMs was of course impossible, Windows barely chugs along with 512 MB of RAM.
Again. People are grossly overestimating their computing needs nowadays.
