There are some advantages for sure. It takes less energy to run them and makes for a fun hobby. Truckcoin's cap is 200 coins and it has been running a few years too so the inflation rate is dropping.

I think someone was posting about running Hyperstake on the Pi but I'm not sure how that worked out. Any coin that has been running for a few years takes some memory to stake and I'm not sure if the Pi will be able to handle it well.

I've heard that Hobonickels is working on a potential solution with a light wallet containing your private keys that could run on cell phones (or maybe the Pi?) talking to a web based staking wallet. I'm not sure of details on when this might happen.
