Simon Willisons’ got some pretty good reasons why you want a Mac if you’re planning on attending a conference.
Me, personally, I’m totally stoked about the whole Rendevouz (ZeroConf) thing. Definitely would have made a number of classes in college more interesting and fruitful.
ON THAT NOTE: Taking into consideration that the college student can get a pretty good deal on a Mac, I wonder how many are using Rendevouz? If you factor in Bluetooth and AdHoc Wifi networks you’ve made the quantum leap from “the computer that won’t print on the colleges computers” to “I beat you all to the printer cos I connected with Bluetooth from my seat and printed 5 minutes ago”.
