WWDC by the numbers (Updated)

Apple kicked off WWDC in a big way with 5,200 attendees who snagged all the tickets in a mere two hours. Unlike previous years, Jobs dove right into Mac OS X Lion without his traditional summary of the amazing things Apple has done. We watched the live stream like a hawk and gleaned out the pertinent stats that show how well Apple is performing across its product groups. Here's what we learned from Jobs and company:

• 54 million Mac users worldwide

• Mac grew 28% while PC market shrank 1%

• Mac sales are 73% notebooks, 27% desktops.

• Mac App Store is now the #1 PC software channel over Best Buy and Walmart

• Pixelmator made $1 million in its first 20 days, quadrupling its revenue.

• over 200 million iOS devices sold

• more than 44% of installed mobile user base

• 25 million iPads in first 14 months

• 15 billion songs sold in the iTunes store

• #1 music retailer in the world

• iBookstore downloads topped 130 million; six publishers on board

• 425,000 apps in the App Store; 90,00 are for the iPad

• 14 billion apps downloaded from the App Store

• Apple paid out more than US$2.5 billion to devs

• 225 million iTunes accounts

• 50 million Game Center users

• iPhone 4 is number two camera, not just smartphone camera, but camera on Flickr

• OS X Lion has over 250 new features and 3,000 APIs

• IOS 5 has over 200 new features and 1,500 APIs

Not too shabby for a company long considered the underdog.
