With the price drop, I'd consider grabbing one instead of a DSi, but then I've heard a lot of murmurs that Nintendo intends to monitor and ban, or possibly even brick units, that are used to run unauthorized software (i.e. pirated stuff, which I don't care about; and homebrew which is all I care about).

I hate to break it to you, but emulation is piracy, especially games you can buy in the Nintendo eStore. Just saying. :-)
