I was in Best Buy in Louisville, KY this evening(Shelbyville Road/St. Matthews) and they had a gold model on display. I didn't inquire about overall in-store availability, as I mostly just wanted to play with it and get a feel for some of the new features that have been so talked about.
BTW, although this is not the computer for me(and I never expected it to be) I was really impressed with the new trackpad. On the default settings(medium w/feedback), it does indeed feel just like the one on my MBP, and were it not for the fact that I knew it was different I'd think it was the same design. Of course, you can click at the top of the trackpad, which is something the older design doesn't allow. Just like the old Apple Pro mouse(which was supposed to have adjustable click pressure), at least with a few minutes of playing in store, I didn't notice much difference between "soft" and "firm" for the click setting.
On the other hand, the short travel of the keys on the keyboard bugged me. I could probably get used to it. I'm probably a bit "out of calibration" considering that I use an AEKII daily, and plug a Unicomp Model M into my MBP when I'm typing very much.
But, that's just my impression from about 10 minutes of playtime in the store.
