I do and I don't.
Do I want a more powerful system that can play a wider variety of games? Yes I do.
But I don't want to buy the N3DS for a two reasons.
1.) I think the system is hideous. I'm sorry, but I think it's a bigger eyesore than the 2DS. I don't like the button placement, stylus placement, or cartridge placement. I think that the 3DS XL has the best layout, tbh. I love my original 3DS but I agree that my systems button placements aren't good, but I prefer them over the new 3DS (though I really dislike my start/select/home buttons. I don't mind my stylus placement but I can see how having it on the side like what the XL does could be better. I've never played a game where I needed to whip out my stylus super quick) plus I am one of those people that actually enjoys the glossiness of my original 3DS lol. I know a lot of people don't but I don't like the matte finish the XL and N3DS have. I think the faceplates might be cool though. Have Kirby on my N3DS would be snazzy.
2.) I am one of those people who think that this was a total jerk move by Nintendo. I've owned my system since it's first price drop (so pretty early but not early enough to be an ambassador) and it still works wonderfully. Aside from a few small scratches on the outside from when I've dropped it it still looks brand new too. I have no reason to buy the N3DS because mine still works fabulously. It would be a waste for me to buy a brand new 3DS when there is nothing wrong with mine, except for it's inability to play nintendo's new exclusive games (I really don't care for the c-stick, I'm a casual gamer and chances are I won't have a use for it given the games I play)
I think the only thing that'll persuade me to get it is if they end up releasing a bunch of exclusives that I really want. For now that's not an issue. I've never played Xenoblade so if I want to try it I'll just get the Wii version. Or if my 3DS breaks or gets lost - then I'll just upgrade to the N3DS instead of buying an old system. For now though, I still love my original 3DS in pearl pink. It plays the games I want to play just fine and I like the way it looks. The only annoyance is trying to play the GB HM games I have because I have I press the start and select buttons. >~>
