Can we please stop acting like it's a foregone conclusion that everyone's Wii/3DS/Vita/PSP/Whatever is off in a corner collecting dust?
Sure, if you're splitting your time between 3 consoles, a PC, 2 handhelds and 2 smartphone platforms, yeah, not everything is going to get the attention it deserves. People like me don't have that kind of time or monetary budget, we can't buy hardware we're not prepared to commit to.
As it stands, I've gotten hundreds of hours of enjoyment out of my 3DS thus far, playing an even combination of first and third party games in a diverse range of genres. I've been burned on a couple titles, (the Sims3 for 3DS is a really, really shoddy port with most of the content stripped out) but I'd say at a ratio that's about on par with the PC and 360.
