PDC 2009: What have we learned this week?

What will Office Web Apps do? Less than we once thought, apparently. The extent to which you can view "rich content" created with real Office applications, in Office Web Apps, apparently remains strong. But since O Web will be free to everyone (for sensible reasons) the ability to create the same depth of rich content online will be artificially limited.

Since many businesses utilize Excel as a type of database, or as a window into their databases elsewhere, this means the utility of that product online will be most restricted. Word may suffer the least, however, as the need to compose respectable looking correspondence from anywhere one happens to be, is a pressing need that Word Web App can easily fulfill.

Making the case for Office 2010. We expected Microsoft Office to be the star of Wednesday's keynote, with demos of new functionality that, if it wasn't major, would at least have been advertised as fresh and new. It was not to be. Although we did have an opportunity to speak with an Office product manager (more on that in the coming days), the message Microsoft was sending this year was very different.

In the past, folks used to ask why a consumer applications suite was being prominently featured at a conference geared towards developers. The answer from Microsoft typically was, because Office is a platform, and developers build to platforms. The message Microsoft sent this year was that Office was not a platform. And that's a problem, because if that's true, there's no conference for Office. The excuse for the lack of Windows Mobile news was that it was a topic for MIX, the conference for Web developers set for next spring in Las Vegas.

So does Office wait for TechEd? All of a sudden, this major profit center seems homeless.

There was a little buzz devoted to something called the Outlook Social Connector plug-in, a new tool for integrating individuals' social media contacts within Office's communications app. Deals with social network hosts such as LinkedIn were announced. In one respect, that does address consumer concerns; in another, it's a little ironic. Here we have a situation where people take the time to broadcast their identities over multiple social services on purposes as a way to spread out...only to discover the need for a kind of "identity vacuum" to pull them back in again to one cohesive chord.

What we did see from the Office 2010 public beta (released Monday, then released Tuesday, then "launched" Wednesday) let us know that if Microsoft truly is listening to its customers and acting on their telemetry, then the word they're saying most often must be, "Whoa!"

During the Technical Preview phase, Microsoft unveiled its BackStage concept -- a way of organizing all the preparatory content of an application, such as print preview and preferences, in a more dimly-lit, cooler arrangement, making you almost want to whisper when you talk about it. The screenshot above shows BackStage in the Excel 2010 Technical Preview.

This is the same BackStage in Excel 2010 Beta 1. It's more conservative in several obvious regards, including the staging. But notice also something very important: The "Office button," which premiered in Office 2007 and which flattened down to become an icon menu tab in the Tech Preview, has now returned to being the File menu. If customers have been asking, "Where's File/Save?" then you have to wonder when they started asking, and how long they've been at it.

The new flavor of Visual Studio is already the old flavor. When you're dealing with a development platform unto itself, the beta version is often, unofficially but certainly, the working edition for many developers. And VS 2010 is already on Beta 2 now. More than one session presenter this week asked for shows of hands as to how many folks were already using Beta 2 as their development platform -- and in each case, a majority of everyone's hands were raised.

Will virtualization envelop Windows? Hell if I know. One of the hottest topics of prior conferences was something of a dud this year, and that's not good for a company that is actually behind in its ability to virtualize 64-bit platforms on 32-bit systems -- a feature Sun's VirtualBox and VMware already provide. But once the problem of absence of live migration in Hyper-V was kicked, virtualization took something of a breather this year, though it wasn't off the radar altogether.

The push toward online identity. Indeed, this ended up being the wildcard topic of the show. The principal security and architectural problem faced not only by developers but administrators as well, is enabling a secure single sign-on platform for local and remote applications. With multiple vendors supporting even more authentication protocols than there are vendors -- or so it appears -- this goal would seem impossible to achieve.

Microsoft is working to address this in its upcoming Windows Identity Foundation library, which will require the push of Active Directory Federation Services 2.0 -- a way to get AD out there to servers that aren't Windows. But just getting all hosted apps vendors on-board with AD is a colossal task, made more difficult by a "competitive" spirit among application and security vendors that works against the very spirit of communication and federation they need to accomplish the goal of common identity. We will be talking more about this in the coming days, because we learned a lot about this from PDC.

Now, there's something I'm missing. Yes, Scott Guthrie, I know I missed you in my list of headliners...and I'm sorry, it was inadvertent, and I apologize. Though I do know Brian Goldfarb gave you heck about it. But there's something else, let's see, I'm trying to recall...help me out, Brian...

Oh thank you, Scott, much obliged. Silverlight 4. This one should have been on our radar for certain. Silverlight stole the show on Wednesday, and was much of the talk among developers on Thursday. The new version will provide 1080p video, which everyone wanted. And it will provide authenticated access to system services outside the sandbox, which everyone wants.

If Office Web Apps were to run on Silverlight 4, you would get access to the right-click context menu -- a critical feature of regular Office 2007 and Office 2010 that's difficult to make up for with the ribbon alone. S4's access to system devices will make it feasible for developers to craft iTunes-like smartphone applications for devices that are tethered to PCs...and maybe even devices running on smartphones themselves, and not just Windows Phones.

Which reminds me, there was that one Guthrie demo Wednesday that bit the bottom of the bit bucket, with that cool looking phone. Did anyone ever make that work...Brian Goldfarb to the rescue once again. Yes, it is indeed possible to perform adaptive streaming of movies to the iPhone using Silverlight. We talked at length with Goldfarb (more on that too in coming days), and here's a preview of coming attractions:

"We've worked with Apple to create a server-side-based solution with IIS Media Services; and what we're doing is taking content that's encoded for smooth streaming and enabling the content owner to say, 'I want to enable the iPhone.'"

It was certainly more of an evolutionary than a revolutionary tone at this year's PDC, but attendees seemed comfortable with that this time around. Here was one strange phenomenon we've never noticed before: Attendance increased with later days. Wednesday attendance was noticeably higher for sessions and the keynote than for the previous day, and that was despite news of the big laptop giveaway being kept under lock and key. And Thursday -- which has often been a day for "leftovers" -- ended up being packed as well, including with attendees who brought those shiny new Acer multitouch laptops with them.

Now, there's something that hasn't been touched on: Acer. Think about that for a moment. This is the same company that publicly dissed Vista in 2006 for being a non-event for consumers, practically leading the wave for the complaints that were to follow. And here it is lending its name to an event that not only promotes Windows 7, but prototypes its proper use (from Microsoft's perspective) in all computing. Microsoft let Acer show everyone else how quick bootup and clean performance are supposed to be done.

That's the biggest indicator of Lessons Learned we saw all week.
