For awhile now I have been considering getting a PSP or DSi. I have played very little on both handhelds so I'm still on the fence. I like the fact that PSP now has the option for downloads (UMD isnt a deal breaker for me), but from what I have played on DS, it seems to have a wider library of genres. I guess they are two different experiences, but DS has the top notch Nintendo franchises (that seem to have reviewed well) made specifically for DS, and the PSP has a lot of ports from PSone and PS2. Anything I should know about either handheld? Flaws? Experiences? Lets me know.
