It's not solely because of piracy . DS sells software just fine even though piracy has been easier on DS than PSP, PS2 sold software just fine even though it had massive piracy, Wii, PS1 etc. Bigger reason for lack of PSP software sales is its game library. Yes there are some critically amazing games but even these are seen little watered down PS2 versions with nothing unique. They are typically home console games turned to portable but with inferior graphics and gameplay. Nintendo has been able to create games that work better on handheld. Also first party line up for PSP has been pretty much disaster. Compare that to PS3 and it has been pretty bad. It feels that when PS3 started to stuggle Sony somehow forgot they had PSP and it has been that way.

Exactly, and look at Japan software sales compared to the West on PSP, they have games that appeal to handheld J-culture (Monster Hunter especially) and that software sells like hotcakes... What Sony needs to do about the PSP2 is to appeal to handheld W-culture (game design especially but one thing i would do is to use cartridges instead of UMDs, loading times, noise and poor battery life are not for handhelds, and UMD compromises all of them)...

Actually, I would say piracy is initially harder on the DS than the PSP and that's what matters.  I assume for the PSP you need a USB cable and who doesn't have one of those (I could be completely wrong here, just assuming)?  For the DS, you have to buy a special cart and then a mini-SD card which both together are fairly expensive.

True, once setup I assume the DS is easier but when we're dealing with cheap, lazy, and selfish pricks in the first place they're probably going to go for the initially easier and cheaper investment.

neh... R4 cards go for around 15 euros and you get a 2gb miniSD card with it... heck it even comes with an usb adapter for the mini-sd card.. you could get them in chabby phonestores or order them online before they were banned in the netherlands..

It would solve my problem of not being able to find certain games. 

Ah, heard they were more expensive than that and buddy told me he had to buy his own mini SD card for whatever he got (DSTwo? I think that sounds right).

Ah..  that's like the most expensive one you can get.. it has its own processor to emulate gba and snes games.. they are planning NES and NeoGeo emulation.. Real Time Saving and E-book support..  that one is around 40 euro..
