Yep. I like a few 3DS games, but sadly they weren't enough for me to keep my 3DS and I ended up selling it last week. The hardware is so bad and ugly, the UI is horrible, no account system, the eShop is a joke, limited demo usage is dumb, region lock, horrendous resolution and the lack of a ps+ like system sucks as well. Lastly, the same thing I said about the DS is obviously valid for the 3DS: I still think a gaming device having two screens is pointless and it just make playing a bit uncomfortable.
All of that being said, I will probably buy a 3DS again late 2014 or early 2015, because games still are the most important aspect of any gaming system and by that time, the 3DS will have a few titles I will definitely want to play (Bravely saga, Persona Q, Smash Bros 4 and any new Pokémon title). It would be sweet if by that time, Nintendo have release a new model with better everything, but that have like 0% of happening.
