At the Consumer Electronics Show in Las Vegas, I sat in on a competition of mobile applications. It was really interesting to see the apps that entrepreneurs and large businesses are putting together these days.

One app enabled women to run simple background checks on men they meet to see if this guy is someone they should go on a date with. By just entering someone's name or phone number, the app presents you with quick and comprehensive criminal background info and can even reveal if the guy owns a house or lives with his parents. The app, designed by data warehousing company Intelius, puts tons of personal background data right at your fingertips.

I find it amazing the various things apps are being developed for. This is something I'm sure will continue to grow in coming years, especially considering Google's recent entry into the smartphone market.
