Review: No shortage of addictive new iPad games

Since the avian menaces invaded Apple's iPhone in December 2009, the game and its spinoffs have been downloaded more than 250 million times.

Since the iPad debuted last April, "Angry Birds HD" has been at or near the top of its Top Paid Apps chart.

The characters have moved on to T-shirts, plush toys and board games, and there's even been talk of a movie or TV show.

There's no way to duplicate such success, although there are enough critter-flinging rip-offs in the App Store to populate a good-sized zoo. But if any company has a shot, it would be Chillingo, the UK-based publisher that picked up "Angry Birds" from Finnish developer Rovio Mobile.
