My g/f got it at launch and I spent some time with the system and frankly I'm unimpressed. The background is a pseudo-3D type. Really all it is, is a multi-layered back drop that gives the appearance of a 3D unit. That aside, the controls are nice, but coming from the DS Lite myself, I like the placement for the stylus on the side because its easier to get to and easier to put away versus the slot being behind the screen like the 3DS.
I played a bit of the Street Fighter 3DS and I dislike parts of the game right from the get go. I'm a fan of the series but the 3DS version is definitely a more casual gamers version than the 360 ones or earlier.
I will give the 3DS credit, it has good sound and the the device itself fits wonderfully in my big hands (unlike the PSP which is hard to hold when pressing certain buttons). Despite my problems with the 3D part of the device, I think the graphics are great but I'm unsure if its any better from the DSi or DS Lite versions (I don't see much difference).
I certainly don't feel this device was worth buying at launch, which is why I'm glad my g/f paid for it and not me
