One of our favorite things to do each year at Macworld Expo is to wander the show floor with no agenda other than to see what we can find. Many of the venders are the same each year, using the expo as a time to launch variations of similar products. That’s fine, but it really starts to get fun when you stumble upon the booth of a hardware or software developer happy to demonstrate something you’ve never seen before. Here are three such finds.

Although Macworld Expo 2010 was confined to just the north hall of Moscone Center this year, that doesn’t mean there wasn’t a wide array of great products. Now that we’ve had a chance to settle down and review our notes and brochures, the Appletell staff in attendance has selected our favorite products of Macworld 2010: a camera card, some competition for AppleTV, and a helicopter that wasn’t even a part of the show.

Gendai Games, in conjunction with IDG and the Macworld Expo, has officially announced the winner of the Macworld 2010 GameSalad Challenge: Stunt Squirrels by Fire Maple Games. The winner was determined by the judges’ decision on Saturday afternoon at Macworld Expo. Stunt Squirrels—a physics puzzler—features blasting death-defying daredevils safely to a goal, while navigating tricky mazes and high-flying obstacles.

iPhone development has created a huge business opportunity for many companies, and the possibilities are only increasing with the announcement of the iPad and constantly improving software. Part of this business involves not only developing applications, but also helping other people develop applications in an easy, hassle-free way. Two companies trying to do this, SachManya and SelfServeApplications, have recently announced new products for this very task.

It’s a wonderful Macworld tradition that each year many exhibitors will have show specials where you can receive additional discounts during and after the show. Some are only available on the show floor, but many are open to any with the inside track. So, each day we will try to find deals we can publish so those of you at home can play along and enjoy a few of the benefits of being at Macworld. Jump past the break to see what we have found so far.

If there’s one thing we’ve taken away thus far from our trip out to Macworld 2010 in San Francisco, it’s that the show has been a success. We’ll have a roundup article later this weekend with details on that, but in the meantime, we wanted to let everyone back home have a chance to see what’s going on in Moscone this year on the show floor, at the media events, and around the city (now complete with booth babe).

On Friday morning of MacWorld 2010, Guy Kawasaki showcased five iPhone/Mac developers and gave each one a chance to show off the innovative things they are doing. Guy is a former “Evangelist” for Apple and is currently the co-founder of Alltop. Let’s take a brief glimpse at the apps and developers that were showcased: Square, Hearplanet, Boinx TV, Bing and Bill Atkinson PhotoCard.

Apple may not have used Macworld Expo to announce the iPad, but that doesn’t mean it isn’t present. Cases are all over the show floor and many developers have been happy to discuss their iPad plans. We’ll have more on that later this weekend. But today, IDG held a special event roundtable with some of the precious few who have actually had their hands on one. What did they have to tell us about the forthcoming device? Not much at all.

John Gruber, author of Daring Fireball outlined what he felt were the top ten issues facing Apple (but not necessarily with solutions) at his Macworld 2010 presentation. In no particular order (except for the first, biggest, one) they included Steve Jobs, the future of computers, figuring out why Mobile Me exists, and the difference between safety and security.

Film maker Kevin Smith came to Macworld 2010 on Thursday, joking that he was invited to warm up the crowd for Steve Jobs, to whom he was excited to talk and pitch movie ideas. Smith spent the next hour and a half taking questions from the audience, much like on his tours of An Evening with Kevin Smith. No topic was taboo, as Smith talked and joked freely about his weight, recreational drug use, and reputation in Hollywood.
