The rp3 is super neat. It's a very low cost linux that you can keep always running. I mostly use it as a media server and for torrents. I can listen to music or manage torrents from any place - when connected to the home network or outside of it.
Overall, it's a very fun thing to play around with. I don't think it can be used for anything serious, but considering its price, you have nothing to lose.
