The instability issues with Second Life cripple what could otherwise be a rich user experience. Even when it works, it feels creaky and burdened. Not surprising, given the nature of 3D graphics, let alone the streaming of user created content in real-time. The other major issue is that while the 3d environment works very well for social interaction, It isn't so great for interacting with more traditional infomation like the written word. If they could integrate some tools to more seamlessly interact with 2d data like webpages, then heck, I'd spend all day in there.
