Yes, I absolutely LOVE the 3DS! (I have loved all Nintendo's handhelds, from Gameboy via Gameboys Pocket and Color, Advance, SP, and finally DS and 3DS; I still haven't gotten a New 3DS though).
I think the 3DS is absolutely perfect, nothing less. It's light enough to hold so that it doesn't feel heavy (looking at you, original Gameboy!), and the buttons are well placed, and the size very good for my hands.
I have quite a few games for it. The ones I play the most are the series Pokemon, Pokemon Mystery Dungeon, Dragon Quest, Rune Factory, Harvest Moon, Animal Crossing, and the stand alone game Fantasy Life.
