If you've been trying to convince your casual-minded significant other that you don't just want, but rather need, a DSi in addition to the DS you own, your moment may have just arrived. PopCap has announced that it'll be bringing its stupefyingly popular puzzle titles Bookworm and Bejeweled Twist to DSiWare this month and the next, respectively.

Sure, they'll be out later on retail shelves (December 1, 2009 for Bookworm and Q1 2010 for Bejeweled Twist), but if you're going to score yourself a new DSi, your significant other can never know this. They can never, ever know.
