Right now a lot of people look at BTC as a get rich scheme, which is probably playing into the instability of the price per coin (don't quote me though, I'm not an econ guy). I think most of us are waiting for more places to accept bitcoins, since the main thing you can do with them is trade them on mtgox or some other echange site. There's also Silk Road, which I still haven't checked out.
For me, bitcoin is fun. I enjoy building computers and browsing hardware; bitcoin convinced me to make another high end system and make a multiple gpu computer for a change. It's also fun for me to help with hardware and computer related issues.
If bitcoin doesn't take off, then I'm not at a loss. I've almost evened out with my hardware, and I'm enjoying the maintenance of my mining rig. If I make some money off of it, then that'd be awesome. If you adopt mining or bitcoin for fun, I'm sure you will get something out of it. If you invest in it thinking in a week you'll be rolling in $20s, then you'll probably be disappointed.
