My reasons for wanting to take the trip are two-fold. 1. The trip itself. 2. A new computer. I'm sure the Mac-geeks know the new PowerBooks came out this week, and I really, really want the new 15" one. I'm holding off until 10.3 (Panther) ships, since I don't want to buy the machine then turn around and have to upgrade the OS a month or so later. Apple's said it'll be shipping by the end of the year, so I'd imagine making it an Xmas purchase would pretty much guarantee I'd get what I want.
The reason I'm considering getting it in Japan is because Apple's Korea pricing sucks. They haven't listed prices for the new models yet, but comparing the old 15" price in Korea to the new 15" price in Japan, Japan is about $550 cheaper. ($2700 vs. $3250) If I'm going to spend an extra $550, I may as well get a trip out of it.

The object of my affection:

So really, I'm just wondering if there's anything interesting to do in Tokyo over the Xmas days (25-28 is what I'm looking at) - expat gatherings, anything put on by the city, etc. - or should I just make it a shopping trip and see more of the city?
