The Silicon Valley tech corps is doubtless too exhausted and giddy from liveblogging today's Steve Jobs keynote at Apple's Worldwide Developers Conference to rake it over the coals. Please, allow us. Here's a recap of what Jobs announced — and how much impact it will have on the Valley.1. Almost a million Apple developers. Jobs threw this out casually, but the number of programmers registered with Apple for updates is up 25 percent in a year. That's a huge victory for Apple, which has long suffered from a lack of Mac apps compared to Windows. Impact: 9 Surprise: 5 2. Apple's got game. Every five years or so, Jobs trots out John Carmack of Id Software, who proclaims his renewed enthusiasm for the Mac platform. The only problem: Jobs does this only every five years or so. Today's promises of more Mac games should be viewed in that light: Apple owes its weak lineup of Mac games to its on-again, off-again approach to videogame developers. Impact: 3 Surprise: 1 3. Log into your Mac from anywhere. Most of Jobs's Mac OS X Leopard was a rehash of already announced features. But this was new and significant: You'll be able to use Apple's .Mac service to log into your home Mac from any other Mac. That's a good reason for families with one Mac to add another. In other words, unlike most of Leopard's ho-hum new features, this one could actually lead to more Mac sales. Impact: 7 Surprise: 10 4. iPhone will run Web apps. A brilliant move that at once weakens Microsoft, strengthens Google, and quiets critics: Apple will let Ajax-ified Web applications like Gmail run on the iPhone. Some had demanded that Apple open up the iPhone to allow programmers to write native applications, a move Jobs resisted because of security and bandwidth concerns. By making the iPhone a platform for Web apps, Jobs is giving that nascent software platform a boost, while discouraging programmers from writing Windows-only apps. Impact: 9 Surprise: 8 5. Google and Apple integration — not! Less than two hours ago, every tech pundit on the planet was predicting that Google ZCEO Eric Schmidt would take the stage, Google and Apple would strike a deal to integrate Google's back-end Web services like email into the Mac, and Apple would make its .Mac service free. He didn't show, and it didn't happen. Impact: 0 Surprise: 10
