Well, I bit the bullet and ordered my iMac Core Duo. In a way, I wanted to wait, for future announcements to see what happens to Mac Mini and if there would be a smaller MacBook Pro. However, I felt this was a well-rounded machine, and I could always sell it, in the future, if need be.
The Amazon price was great after rebate, plus $20 more off with A9 reward, plus I had some gift certificates, and I paid $4 for overnight shipping. It should be here tomorrow (January 25).
I got the 17 inch because I wanted to keep my 20-inch ACD, so I will connect it to the iMac. I'm keeping my Powerbook to use around the house and for travel. I love my Powerbook, and it is hard to say it will no longer be my #1 Mac. However, I'm thinking I might even use my Powerbook more around the house now. With it has my main machine I have to disconnect display, USB connections, Firewire connections, audio out, power, etc. whenever i want to take it somewhere else in the house. However, now that it will only be connected to power, its just one plug to have a mobile mac ready to go. Nice.
I'm going to order memory tonight or tomorrow. I don't know, if I should get a 512 stick, so that it will match the other stick, or gig a 1 gig stick. I might get a 512 stick for now, to save money. I think 1 gig of memory would be enough, for my needs.
On a side note, I wish this thing could boot Windows, so I could sell my PC. Maybe someone will figure it out.
