I too am slowly moving from Microsoft to Linux. The confusing part for me here is that OSX is basically Linux, so I don't understand how a regular Linux GUI Client can be so hard. The advertising also caught me and I think is rather misleading of oDrive. You have a good product but as I see it you are liiting its use by not fully supporting Linux and being too costly. I won't go Premium until full Linux support is there and the cost structure is more reasonable.
