Matt,
I just bought two: one for my home office and one for my work office. I was having trouble with the limited RAM in my previous versions, but I’m up to 16 GB on these. I’m using the 2.8 GHz quad-core processor. In short, I’m very happy so far. The screen is massive, but I’m still waiting on the new tiny video to DVI adapter so I can hook up a second screen.
In addition, I also upgraded my notebook to a new MacBook Pro. I’ve had that about two weeks, and I’ve been very happy. Apple has designed and engineered some marvelous machines. I have 500 G of disk on my MacBook, but I came very close to ordering 256 G of solid-state storage instead. No moving parts!
Cheers,
Tim
