Handheld computing give us a Tetris and Scrabble hybrid, Dasher. On the surface, Dasher is a new data entry interface for devices without keyboards. But in practice, it looks more like a video game, zooming through multicolored rooms to get to each letter, intelligently presenting options for what users are likely to select next. Utilitarian or fun? Download a beta version and check out this cross-breed for yourself. - Eryk Salvaggio
