So how shitty is this thing? I haven't been paying that much attention, but from what I've heard there's a lot of problems.
Eh, it depends a lot on what you're expecting. If you had any expectations of this thing being a serious contender in that it would be a lot better than the PS3/360 and have a fighting chance at getting software designed for high-end PCs and the next Microsoft and Sony platforms, then it's pretty clear that this thing is a joke. If you're expectations are more tempered, then it's kind of up in the air.
There's been a lot of problems and concerns regarding the OS. There have been locks, freezes, network errors, big day 1 patches, and disappointment at the way Network IDs are handled. But, on the other hand, the tablet is kind of nifty for what it is, and you'll get Nintendo games in pseudo-high def which is a noticeable improvement over 480p. The stuff that is there mostly works even if there are long load times.
So, yeah. What do you want from your Nintendo console?
