Mark your iCal's: Apple's annual Worldwide Developer's conference will be held June 6-10, right here in San Francisco at the Moscone Center (apple really likes this place, having held many a launch and conference in this same location).

If you're on Apple's mailing list, you probably already received an email with all the normal fanfare and wonder of an email from Apple. Brevity is the soul of both Wit and Marketing, and Apple figured that out a long time ago. The tagline for this year's event is "the future of iOS and Mac OS", which presumably has something to do with running out of large jungle cats with which to name the latter.

Phillip Schiller, Apple's SVP of Worldwide Product Marketing:

At this year's conference we are going to unveil the future of iOS and Mac OS. If you are an iOS or Mac OS X software developer, this is the event that you do not want to miss.

Also, if you are a developer, you're going to want to budget accordingly as passes are available for the low low price of $1600. Between their 30% cut on subscription apps, this steep attendance fee, and the shift from esthetically-pleasing and virginal white in their product-line to the now-pervasive industrial black and titanium color scheme, does it seem like Apple is a substantially darker enterprise than it was in the last decade?
