In an earlier post, I conjectured that laptops are "the briefcase of the new millenium". I'm glad to see I'm in good company as none other than Peter Merholz wonders why product designers don't take advantage of laptop mobility. He's also another observer of the growing trend towards the laptop showing up in leisure time, probably due to its capabilities as a coordination (synching with others), navigation (maps, directions), and interstitial (dvds, games, photo munging) tool.
Guilty as charged for taking the laptop on vacation.
