Brett is doing something I do, which is using Sync for a personal cloud because we have Mac minis in a colocation facility. It works exceedingly well for me.
It’s also amazingly fast. Sitting at home I can upload something I save to my server from my iPhone (via the new Transmit iOS app) and it syncs for that Mac mini server back to my MacBook Pro almost instantly. It’s quite incredible.
(I use the Mac mini server because it is always running. Also the Sync iOS app is really slow in my use.)
