I'm sure there has been threads about the 3DS already but I got mine on June 17th and I thought I'd put here what I though tof it and hopefully get a few friend codes.
The 3DS has been insulted endlessly, saying it's not worth the money. Does my head get hurt? Yes. But only when I'm an idiot and use the 3D when I'm looking away. Half the time my 3D is off, and it's still worth every penny. My DS Lite was 250 when it came out and all it added was slickness. This adds a circle pad which is so much more awesome then you probably think. It has games that more for hardcore gamers instead of anything with Mario on the cover like the DS before. It allows you to make Miis and sort them, which you couldn't do on the Wii. You can make them from a photo which proves to be more fun then it sounds. After a few seconds, and I mean seconds, of tweaking you have your Mii in half the time it took before. The top screen is wider and the stylus is more accurate.
Speaking of games, right now I have Nintendogs and Cats, Zelda, and Street Fighter. All games are very fun, yet so far Zelda is the best. A lot of people say they ruined it but I feel it adds just the right splash of new but it still keeps its nostalgia. Nintendogs and Cats seems too familiar to some, but I like the newer, more realistic and fun walking system and series of stores available. With trainer points now you can unlock new breeds by loving your dog instead of having to connect with other players. The cats are lazy and don't get you money, but cute. My entire body melted the first time it chased a ball of yarn, turned around, and smiled at me.
It's still annoying how in the game you can only enter a competition twice, and that's your only real source of money. That's why Zelda is the only real awesome game to me. I play Nintendogs for an hour or so in the morning, then when I run out of things to do because it's dumb like that, I switch to Zelda.
The AR games are enough to last you at least 3 days without a game, especially fishing. I only need one more freaking fish to finish my collection

. Anyway, people complain it's hard to use, as is the 3D, but they made the ranges specifically because that's what comes naturally. Just play from the angle and distance you would if there was no limit. You'd be surprised.
The games coming out this fall look amazing, I've been waiting for a new Luigi's Mansion and I grew up with Star Fox. Mario Kart's a rehash but it looks like an okay buy. Super Mario adds some cool stuff but Kid Icarus is the one I want. I had an emulator of the original games before Pit even appeared in Super Smash Bros, beginning his comeback. I'll be the first one you see playing that release.
The online store for the 3DS is pretty lame, but I just ignore that and the music app. The camera app is pretty fun for a while then it gets boring.
Streetpass is cool because as little as I go out, I go to Gamestop to pick up a game and get home to find I passed someone with a 3DS. Wow! I also shake my 3DS for playcoins to use them on heroes for Find Mii, where you use found people on Streetpass or a hired hero (costs 2 playcoins, you get one for every hundred 'steps'. You can only get 10 playcoins per day) to fight ghosts until you reach your goal.
I think that's all I have to talk about but overall the 3DS is worth every penny. The 3D, when used, is interesting. Things don't jump out at you, your immersed. Every last bell and whistle makes me pee my pants a little and as my brother (Shadowtroid) said, enough little things can make something that doesn't seem good on the surface amazing.
My friend code is 0602 - 6365 - 7091
To be my friend you must request me and I must request you, so if you are one of the few who one a 3DS please place it below. You can feel free to ask questions or state opinions on the console.
Thank you.
