This is the first thing I thought of when I saw the new higher-price for the entry level Mac Pro.
How many "average" computer buyers are ever going to be aware of the single proc option? Very very few. You go to Apple's site and all you see is $2799. The press release: $2799. Yes the option is there, but again, it's really just for the pros who may not need all those cores.
For all intents and purposes, you have the all-in-one at $1199 and the pro model at $2799. Huge disparity there.
Will it really be a mid-tower? Who knows. It might just be something completely different. People are talking about a beefier
TV. *shrug* Again, I reiterate: There is a sizable segment of the population who don't want to buy another monitor along with their Mac. They already have monitors. They, such as myself, want something like a Mac Mini with the graphic capability of the iMac, or better. Look at the news articles that show Apple's market share rising, about folks disappointed in Vista and are looking to switch. Out of that potentially huge market, a vast majority will have monitors already. Some will be satisfied with the Mac Mini, but others will want more and a $2800 Mac Pro is too big a bill to swallow.
All I know is that I was set to place an order today for a Mac Pro, and now I'm waiting until after the keynote, just in case.
