Did the word free in the headline grab your attention, or was it the cake? Either way, Amazon's Appstore is throwing a party to mark its second birthday, and there's a goody bag of software for anyone who attends. It's been a good month for Android users, as Google's Play store had its own shindig recently, and like last year, Amazon's been treating Appstore patrons to discounts all week. For its official anniversary today, though, a tray-full of apps can be downloaded gratis. Admittedly, the selection isn't fantastic, but you should find one or two things worth at least the time it takes to click 'em -- Chu Chu Rocket, may we suggest (long live Dreamcast!). Remember, you've gotta be quick, as the offers expire at the end of the day. But enough from us. Head to the source link for cake and more.
