Oh "boy" do I love the Arduboy. First of all i love the form factor,it is exactly the size of a credit card, just thicker so it fits perfectly in my wallet, the battery life is also really good actually for it's size, about 5-6 hours i believe. de buttons are really nice and clicky, it is so sturdy, pretty much indestructible. the FX version also has so much more than the 250+ games as advertised, a bunch of cool programs like from using your arduboy as keyboard or mouse or gamepad input, to using it as an egg timer to prefectly cook your eggs and on top of that, whatever else you van imagine and program pretty much, all on this little thing. I now spend more time gaming on the arduboy than I do on my pc. This would be an awesome gift to anyone who is into retro things or programmers or even kids, and they could learn a lot from it too.
