Airports of the future hold the promise of doing away with long waits to get bags after a flight and long lines at check-in, through the use of Near Field Communication (NFC) technology. The concept of one-touch check-in would utilize smart phone and PC tablet technology to allow travelers to simply swipe their devices across an NFC reader in order to check into a flight. Another high-tech innovation on the horizon is permanent baggage tags using RFID technology.

This would mean that if your bag goes missing or if there are a lot of flight delays and cancellations, airlines and airports would be able to use RFID to track your bags through the airport or on board aircraft. The tags would also contain a lot of information about you, including your contact details and frequent flyer status.

This year there are more options to watch TV on your PC tablet, smartphone, or PC. For instance, premium cable giant HBO has announced that their "HBO anywhere" concept called HBO Go is now available for Apple iOS and Android. Now any HBO subscriber with an Apple device, Android smartphone or tablet or up-to-date browser on a Mac or PC can watch virtually every program in the HBO catalog while away from their TV.

This is not a sampler or collection of clips, but rather full seasons and full episodes of the most popular shows like "Game of Thrones" and "Entourage". The service breaks down the shows into categories such as movies, series, comedy, sports, documentaries and late night, but show availability can be inconsistent depending on whether you're viewing programs via mobile device, computer or your cable service's on-demand feature.

An influential technology analyst says that tablets like the iPad computer are cannibalizing sales of notebooks, with over 30% of buyers reportedly using the devices as notebook replacements. Deutsche Bank analyst Chris Whitmore said that strong tablet computer sales would slow PC sales growth to 4% this year, which is down from a previous estimate of 11%. Tablet sales on the other hand, were expected to reach 45 million units, with 70% expected to be sold by Apple.

PC Tablet sales in 2012 are projected to climb to 70 million units, with PC sales increasing by just7%. Whitmore also predicted that Apple's tablet would remain dominant, and easily beat back challenges from competitors. He speculated that iPad challengers would either have to undercut on price, with negative margin implications, or offer a superior product in order to compete.
