You can feel it in the air. Mac sect members eagerly awaiting the next pearl of genius to drop at the Apple Worldwide Developers Conference, which is happening right now at the Moscone Center. (Today's frenzy even managed to temporarily shutdown Digg.) Since your editor is a PC user, naturally, he only cares about the WWDC after-parties' amuse-bouche platters. But what say you, Apple fans? What's the hub, bub? What will be unleashed this year? Something light-weight and irresistibly twee yet hip, we hope. And for those of you who want to follow what's going on today through the 12th at the conference, check out Laughing Squid, gdgt, MacRumors, Macworld, Gizmodo, VentureBeat, the Mac Observer, or #apple for more information.
