Great news.
Well, I mean, if you're going to use a USB to install games on this thing, why bother getting it to begin with? Why not just stick with an emulator?
I've yet to grasp why people would want this thing to begin with, knock yourselves out though.
I'm guessing you're both being purposefully obtuse since the device doesn't appeal to you personally, but maybe you actually don't get it. So here you go:
1. Real, brand-new NES controller.
2. Minimal setup even with the softmod hack.
3. Excellently presented UI.
4. Looks like a real, brand-new NES, but cuter.
5. Generally high quality, accurate emulation without having to dick around with any settings or configuration. (This point is a subject of controversy, given some people reporting lag, and others reporting none.)
6. HDMI video output with no fuss.
7. 3 easy-to-understand display modes that will suit 99% of people's needs, instead of the 50 different scalars, filters, and display modes that you're inundated with in most emulators.
8. Being developed by Nintendo lends a certain air of authenticity to the product compared to the homebrew hobbyist vibe the other solutions give off, whether deserved or not.
