I've only had the 3DS since this January and I'm getting a bit tired of it. I don't like the operating system and most games, well, the ones that didn't get worse, are only incrementally--not mind-blowingly--better than the NDS.
So, 5 years since the 3DS came out and the hombrew/flaschcart scene is far from mature. I wonder how much longer it will take...i.e. before nintendo makes something new and stops caring about this device family? I'm sick of Sky, Gateway, and the e-shop. I like how with GBA, you just physically buy your aftermarket game, stick it in and it works. Even got a decent flashcart, assuming you can find someplace that still sells it! No wifi, street crap, spot piss, social networking Miiii rubbish, or online updates.
A big part of why I like console gaming (over PC games) was the plug-n-play. Seems like the result of lots of hard work, both on the nintendo side and on the hacking side, is making the 3DS as flakey and screwed-up as your typical office PC. Forget having an operating system, suspend/resume, netflix/assbook clients, dumb PDA software: all efforts should concentrate on hardware and game design, not stupid frills nobody asked for.
