Outside of a slew of new game announcements for the PS3 and an engineering prototype of a new controller, Sony also revealed that PSPgo an PSP-3000 users will be able to download a new music app called "SensMe Channels," a mood-based music recommendation system, and a new Windows-specific PSP content management application.

During the first few months of the iPhone and iPod touch's run with the App Store, many people pooh-poohed the idea that Apple could complete with Sony or Nintendo for the hearts and minds of mobile game players, but it's become readily apparent in recent months, with comments from Apple executives supporting this notion, that the iPod touch, especially, really is a game-changing device -- pardon the pun.

But as time has gone on, it's plain to see that Sony, anyway, recognizes the opportunities and challenges that Apple presents. So it seems only fitting that at a trade show that will, to a certain extent, emphasize publishers who are creating content for the iPhone and iPod touch, that Sony should also showcase its latest portable device which also emphasizes downloadable content.

Sony isn't throwing out the baby with the bathwater just yet, however. With the PSP-3000 still available for the foreseeable future, Sony's simply hedging its bets with the PSPgo, presuming that some of its customers will trade the higher price and smaller dimensions for the inability to play any legacy games or movies they can use with other PSPs.
