In the vacuum of the month before the doors opened, nobody could tell how spry the old guy’s step was going to be yesterday. The conference organizers invited the right people, to be sure. They got an Emmy winner in David Pogue to kick off the opening day with a show so complete it even included a play about Steve Jobs, written as a parody of It’s a Wonderful Life. They got Levar Burton to play Steve Jobs, so the actor who created Geordi La Forge on Star Trek could swap adulation with Pogue. “I can’t believe I get to meet you,” they each said.

But it’s one thing to put on a good one-act and another to fill the seats. A few hundred yards away from the play, the bodies were thick in the center of a bustling Macworld 2010 Expo floor. “Steve Jobs isn’t here,” Pogue said to start his keynote. But the Apple faithful were, and probably will be even more by tomorrow, the first weekend day in decades for this conference.

You had to be patient, in the face of the Cool New Stuff all around, to squeeze through some aisles and into some sessions. Like Burton, though, people seemed to know that this meeting about the Mac has roots, deep enough to weather the chill Apple showed to the show.

Burton came into the public’s eye the year before the Mac was born, the Reading Rainbow host who’s now in his 50s and producing. Pogue is 46, and neither fellow looked anything but genuine in his child-like ardor for Apple’s solutions. Out on the expo floor there were plenty more less famous acolytes and experts to testify to a shinier future, with evidence of their creations on display.

Macworld is so much bigger than just the Mac these days, and what’s been sloughed off of this event isn’t being missed. For every absent Adobe booth there was an expanded Crash Plan exhibit, where the back up company showed a product range wide enough to be free for The People or priced to help corporations protect untold acres of data. Crash Plan was giving out $60 licenses to everybody who visited its booth. Adobe might have been here before, but I never walked away from their booth holding a free tool that could keep my creations alive.

If I ran a company and wanted to save money on my utilities, I would look into the asset management software from Absolute Software. Tucked away into the Enterprise Desktop Alliance booth, the company showed the sort of product you would expect for corporate servers, tracking the use of Macs on a network to show when they could be put to sleep to reduce power consumption. The software scales from a handful of Macs to thousands, in one office or across an organization’s continental network.

The products sold through Dr. Bott include Blue Microphone’s Mikey, emerging in a new model tuned up to grab meeting notes as well as close-up note dictation. It swivels toward the subject of your video you’re taking with the iPhone. It’s got a line-in port to use for phone recording and three “volume” settings on the gadget that plugs into an iPhone or iPod Touch, new gain settings to help you get the sound onto a file headed for your Mac. Once it’s there, the new Scribe software from MacSpeech will help push those spoken words into text. The software was so new to production release that they were burning DVDs at the back of the booth to tuck into boxes. But it was also being sold at about a 40 percent discount.

That sums up the draw of Macworld, for the faithful who’ve come here for years. Something new, unveiled in the sparkle of a sea of the excited, sold at a steep deal and explained in a way the Web can never match. It was enough of a valentine to why we love Apple’s products to bring a tear to this old guy’s eye. Of course, it helped that the moment was echoing It’s a Wonderful Life‘s finale, when “Steve Jobs” learns that there wouldn’t have been the Web, or Wired Magazine, or popular computers, or Pixar, if he hadn’t invented the Mac.

And it helped if you were old enough to know and love the movie as well as the long haul away from that darkest year of 1998, as Pogue’s play pointed out, when Apple lost $1.7 billion and the last non-Jobs CEO was leading the Mac over a cliff. If a Mac’s life could imitate art, the ardor of the audience and attendees here showed a lively pulse for the products of tomorrow, showed today.

It helps if your blog already has an RSS/CSS feed, apparently, something that most blog services include as a tick-box. Yapper promises a means to create that brand-specific app for smartphones and perhaps the iPad too.
