I was thinking about the PSP and the fact that software really doesn't sell on the platform very well. I think that some of this can be attributed to the rampant piracy on the PSP scene, thanks to the ability to boot homebrew OSes and pirated games right off of the PSP's memory sticks (heck, pirated games load faster off of memory stick than they do off of UMD).
Meanwhile, the DS Lite has never had support for external memory cards of any sort, which I'm sure has held back piracy on the platform to a certain degree. On the other hand, the Wii was hacked very quickly, and I'm sure that a lot of that has to do with the ability to get at the Wii's internals via code access on SD Cards.
So my question is, do you think the DSi will be hacked quickly as well? This will be the first SD Card-enabled handheld ever for Nintendo, and the more I think about it the more I think it might be a mistake from a piracy point of view.
