I don't want to maintain my own mail server, but I definitely want to run my own server. The irony is that modern internet infrastructure makes decentralisation _more_ feasible, but software lags behind. Why can't I buy some device for 200€ or so where I store all my data and I receive email? (with the cloud being used only for optional encrypted backups). One can even imagine a decentralised social network running in these devices, with my friends getting updates by polling it periodically (or my device sending updates to their devices). The device would be powered 24h/365d, and if it breaks you just replace it. When I'm out of home, my phone apps would just query the device to get new mail and updates. We shouldn't really _need_ the cloud for many things yet we use it for everything.
