Finally!!!
I have been waiting on this for what feels like forever (other iBooks folks out there probably feel the same) but I am completely satisfied with the specs except for one thing: put the 512 of RAM on one chip. Don't make the loyalists have to go out and almost immediately toss out (or try to sell) to VERY low end 256 chips (we all know that $90 Apple Store upgrade to a gig isn't really as inexpensive as what you can pick up at new egg or a similar retailer).
I don't mind the integrated graphics - honestly, I have to use Boot Camp and Windows (sadly) for work stuff, and the performance of the graphics set is more than satisfactory for the whole Adobe suite, Dreamweaver, etc. I have an Xbox 360 for gaming, so I don't really look towards my computers for gaming solutions (but understand that some of you may be disappointed). I'm just so glad they finally released the damn things and with a week ship time!
Also what's interesting about the GMA 950 RAM sharing is that it does it dynamically according to task. It will use a minimum of 8MB and go all the way up to (what looks like 64) on the MacBook as the system demands it - this has proven to be a great function in the Windows 1/2 of my Mac Mini and the OSX 1/2.
Anyway, this is my first post ever, so pardon the rant, but like a lot of you, the rumor mill/wait for the iBook replacement took FOREVER!! But it's here, I just ordered mine, and will be a happy boy when it shows up (and I think an upcharge of $200 for black is complete BS, so I'm sticking with traditional).
Anyway, hello to all of you - happy birthday to MacBook!
