Well, I have a 17"MBP 2.6GHZ 4Gb and I love it so much that I am often tempted to whack off while looking at it ... and it's enough for what I do, but I was actually awaiting the update for the 24" iMac.
I do video rendering, but I need something reasonably portable and powerful. Not daily, but a few times a month. Hence the MPB.
The Mac Pro is too much of a behemoth + monitor, etc ... and I figured this next update would go Quad. I was going to stick that on the desk and use my MPB as my daily carry laptop instead of my HP.
I bought a 2.93 Ghz QX6800 Core2Quad Dell in June of 2007, and recently sold it due to size and the requirement of multiple boxes to move + the MBP was a reasonable replacement.
In March of 2009, nearly 2 years later, C2D in the the 3Ghz range feels a little like standing in quicksand.
I understand the iMac is somewhere between a desktop and a laptop, but if this upgrade is true, it's not much of an upgrade.
Unless it goes quad, I'll stick with my MBP. Maybe buy an external monitor.
Apple is obsessed with the mass consumer toys, not the computers.
iPhone, iPod, etc.
I keep waiting for them to announce that they will drop the computer line all together.
You can get a hardware equivalent mini for $300 at Office Depot. Fine, it will be larger and won't run OSX, but how much production work can you do on a mini, and how often will you really move it around? My HP laptop will still be more powerful than the Mini, and it was less than $800 with 84000GS Graphics, HDMI port, 4GB RAM, 320GB HD.
I hope they find a way to put a quad into an iMac.
