Actually I understand your point but I don't think you were getting mine. You're right, people in those professions should know computers very well but you have to understand that even graphc designers and musicians don't keep up with what Penryn or Merom or Santa Rosa or the ULED, that's just not what's on top of their list. Most pros know the software they are using, not necessarily the ins and outs and the latest and greatest of the Core 2 Duo processors. I don't think most pros are going into the Apple store asking how much L2 cache is in the latest Intel chip and is it 45 or 65nm? That's just not the norm.
I think you are correct: I have hired many designers, editors, producers, photographers, etc. I have watched them buy and have helped them buy, Macs.
While they are very smart about technical details, most buy when they need a system as opposed to waiting for the latest update. Most are smart enough to know that a 2.6ghz versus 2.8ghz processor change is negligible in day to day photoshop, video and design work.
lacks business sense, and clearly has no clue as to what Apple is doing.
The MBP will be released by March 17th, so yes, WAIT for the MBP. It's coming and soon.
If you are correct, two things:
1) the update will be minor, and
2) that is 5 weeks away. If you need a MBP before then, get it.
We bought our third on December 28 for a project even though a rumored update at MacWorld was forthcoming. Our 17" MBP made us a lot of money in the past 5 weeks.
In our case, waiting would have been a very bad move.
So we bought. We'll keep this one 8 months to a year, and sell it when the REAL MBP makeover comes. At that point, the MBP you wait until March 17 to buy will be really obsolete.
It is an endless cycle.
If you need one right now. Buy.
