A crappy one, because it's not an MP3 player at all. It's strictly an AAC player. If you want to play MP3s, you want a flash card with Moonshell, not a DSi.
And yeah, the region-lock sucks, but I'm not even sure if "DSi exclusive games" will ever exist in cartridge format at all. No flash card can as of yet access the DSi's features, it's possible that booting to a cartridge kicks the DSi into "legacy" mode automatically. Or it could just be that flash card manufacturers want
something out in the meantime until they fully crack the DSi's encryption. It's a matter of whether or not Nintendo designed the DSi's extra stuff to be exclusive to downloadables and firmware, which currently they are. Whether or not Big N left a window open for the future, we don't know.
Well since the power button is smaller than the first DS and is located lower, it lowers the chance of an accidental reset.
You have to hold the power button for just as long on the original DS as you do the slider on the Lite. So you are actually
less prone to accidental resets on the original since you can SEE the button, unless you just can't get it through your head that start and select are on the other side.
In that case, get a DSi. But I hate the Lite's slider. It's EVIL.
