Over the past week, hackers have made substantial progress in their efforts to hack Nintendo's 3DS handheld. Whilethis will have negative consequences for things like piracy, I can see the more practical benefits of getting under the system's skin.
Like getting around the 3DS' region locks for game cartridges.
This is important to those importing games, as well as those who'd like to get a 3DS in a fancy colour scheme that's not yet available in their region.
Nintendo will of course fight moves like this every step of the way, but if you're a regular Joe who would only use this kind of thing to give Nintendo more money, I wouldn't let your conscience weigh you down too heavily if you're excited for this progress.
