I hope you didn't buy that PSP for movie watching only. Sony has officially killed the UMD (Universal Media Disc) format. Sony, who isn't a stranger to failed entertainment formats (Betamax, MiniDisc, soon Blu-Ray) has been losing support for UMD for awhile now. In march, Universal and Paramount stopped releasing its movies on UMD, and Wal-Mart and Best Buy recently decreased their presence in stores. Finally, this week, Target stopped stocking them altogether. In a move that seems almost related, Sony just released a new item called Memory Stick Entertainment Packs, which also contain movies that are playable on the PSP.

I kinda like the idea of a hand-held device for movies, even though most movies don't look that good in such a small display, but I figured the UMD wouldn't last. Too bad mini-DVD players are still too big to bring on the subway. I guess I'll hold out for that next generation of iPods, which are rumored to be horizontal in order to provide a better viewing screen for Apple's upcoming movie downloads.
