With the launch of the iPad 2 yesterday, Apple is set to build on its big lead over competitors in the tablet category. With nearly 15 million original iPads sold last year, the company is estimated to own nearly 90% of the market. But the tablet still can't be considered a mainstream device -- not with roughly 300 million mobile users in the U.S. alone.

The biggest surprise at the iPad 2 launch today may have been Apple CEO Steve Jobs taking the stage after going on his second medical leave in January. The master showman couldn't resist taking the wraps off the upgraded Apple tablet himself, exalting the device (again) as "magical" and taking jabs at the competition in characteristic fashion.

ave you seen the print ads for the JetBlue Getaways program featuring a giant 2D barcode in the center? If you live in New York, they're hard to miss -- since the posters are plastered all over the inside of some subway cars. The ad promotes a sweepstakes contest to win a winter travel package to St. Petersburg/Clearwater in Florida.
