The press covering the NATO conference in Riga (at least on "day zero" or the day before) seem to be a very conformist PC Windows laptop bunch. One thing I always do at these massive press zoos is to scan the press facility for others with Apple Mac laptops. It is a good way to strike up a conversation with a fellow hack.
At the NATO summit press room, I found only three people beside myself with Macs -- I have a 12 inch Powerbook G4, there was a Latvian news photographer (apparently working for AFP) with a larger G4, a Canadian TV "one man band" with a MacBook Pro (17 " ?), and a journalist based in Frankfurt, Germany, but writing on a 12 " Powerbook G4 for his Turkish/German news agency.
Tommorrow may bring in a larger contingent of foreign press and jam the press center (1 700 journalists are said to be accredited). So maybe there will be more Macs around.
