So I finally got the box, unpacked it and migrated my account and files over. Got my memory tonight, so soon I'll have 10GB in there. My first are impressions are highly positive: 1. The biggest difference for me, going from a G5, is that this machine is so quiet, relaxingly quiet. It's nice to give my ear a break from the din of fans. 2. It's snappier overall. 3. It's fast. I rendered a large modo image which took almost nine hours on my old D2.3. On this one, it rendered in 40 minutes! That's 13 times faster! 4. The drives are super easy to insert. Painless. I got a 1TB Seagate on sale from Fry's for $240 so it's now happily inside the tower of power. 5. Love the new keyboard. It is much much better to use than the old ashtray design where the keys would stick. 6. The built-in Bluetooth is very convenient. 7. Very fast to get in sleep mode, and fast to wake. For those still waiting, I feel the pain. But soon you will get it and will really enjoy this system. The wait is worth it. What are your impressions?
