Mp3newswire.net has an interesting review on the Sony PSP used as a personal media player. Many times they reference and compare to Apple’s products directly. While its not a question of better, it’s a question of being “good enough”.
The Sony PSP does not have to be better than Apple as a music player. It just has to be good enough where it is not worth the added expense of purchasing another unit just to do what the PSP already does, play music.
It’s worth the read and it gives an interesting perspective on the industry move toward a single convergence device.
