I got a 3ds a day after christmas and I say that I freaking love it.
The 3d is awesome. all those who say that the 3ds would be better without 3d, you know you can turn it off, and if it didn't have 3d, It wouldn't be a 3ds anymore, would it?
I love the gyroscope stuff, its really really accurate, I think its better than the wii. and it don't have waggle crap either.
the Backwards compatability (which is important, because I likes me pokemanz) is really good IMO, and all those complaining about how the 3ds has to make the image bigger than a 1:1 ratio are dumb. you can just hack yourself an old ass DS screen into your 3ds then. don't complain about having the higher resolution screen. geez. just that doesn't ruin backwards compatability.
the 3d is good. Usually people say that they play it with it on just a bit or even off. for me its 100% 3d on all the time.
the last boss level of Face Raiders pissed me off, but I beat it.
The extending stylus is great, but they put it in a stupid spot. I'm right handed and I have to gake my hand completely off the controlls for me to get it, instead of putting my finger on it and swiping it out, like on the DS lite and the original DS. The buttons on the 3ds are nice and clicky, like on the original DS, which I love, I hated the mushy nasty feeling of the DS lite buttons. I've seen many people say that the wrist strap place is missing, but no, its just on the bottom, I have my original DS wrist strap, which is awesome for Metroid Prime Hunters.
Yep, its awesome and I am satisfied with my purchase.
