As commented, DS Piracy is easier than PSP piracy - £30 at amazon.com gets you a DS cart.

Games are too expensive on the PSP, the DS regularly has new releases @ £20.

PSP has few good games, and as already stated many of those are ports.

The games I play most often on my PSP are games I bought at release, Hot Shots Golf and Wipeout Pure, the most recent game being Hot Shots Golf 2 whic actually contains pretty much all of the content of HSG1 - if I had just got a PSP and got these games at the same time, I would be pretty annoyed at that.

UMD as a movie format was broken from the start, especially when it was possible to transcode movies yourself from the DVD version.

I own one UMD movie - and I have played it once as I went over to a DVD-ripped version as I could carry that on the MS and still have the UMD slot free.

I only got that UMD as I was curious as to what they were like, and because I could get it for a couple of quid due to crazy pricing in HMV, which was £15 for the DVD, £18 for the UMD (who would pay more for a UMD than a DVD) or £20 for a pack with both.

I would possibly pay £5 for a UMD standalone product, but if they regularly bundled the DVD and UMD with a £2 to £3 premium over the normal DVD cost then I would possibly have a whole lot more UMDs.
