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.
