Hope you do not mind my joining the MAC conversation but I thought you might be interested in a different computer idea for travel. I have a 3 pound Sony Vaio TZ170N with a gorgeous screen (although small), an included DVD drive, WiFi, and a battery that lasts about 5 to 6 hours if you are careful. I got it for Panda because of the light weight and features, and love it. It is perfect for storing and editing photos as well as the usual applications. Of course I have to put up with Vista, but it is getting much better than it was at first.
