Well, at 6 grand it is the most money I have ever spent on a computer, by a long shot, so I went into this purchase nervous that I had made a fool hearty purchase (Purchase was 2.5Ghz, 1gig mem, 9800XT, BT, Airport, BT keyboard/mouse, 23" Display) Impressions: 1. Installation was easy. Recognized BT mouse and keyboard relatively easily. It wasn't clear I needed to turn them on DURING the setup phase to be paired, but it didn't take long to figure it out. 2. Quiet as a church mouse 95% of the time. When the fans blow, they blow pretty hard, but it's for quick spurts of time. (I prefer this to a constant droning fan.) 3. This is the fastest machine I have ever owned. I don't do heavy duty stuff, so maybe I am exception since I bought more Mac than I need, but there is almost no latency. It's amazing. 4. 23" Display is breath-taking. I can't get over the colors and the brightness. 5. No build defects as far as I can tell. Bluetooth antenna didn't sit perfectly in it's slot, but the bluetooth seems to work really well. I still have another gig of memory to install--keeping with the theme of this being WAAAY more Mac than I need--so I am sure it will only be faster tomorrow. So how do I feel about spending 6 grand on a Mac? From a product perspective, it is well worth the money. This Mac is simply incredible. From a practicality point of view, I have a little buyer's remorse. Not Apple's fault by any stretch of the imagination, more mine since I spent more than I needed to. But I suspect this feeling will pass, and I will be left with an amazing Mac which will last me and my family for years to come.
