I liked SkyDrive, but its Windows bias is pretty apparent. It won't sync Unix files that would be illegal on Windows (due to e.g. the filename) and the sync algorithm is pretty bad on OSX (frequently running my CPU up to 100%). These are some of the reasons why people distrust the Microsoft brand.
Discounting Microsoft's long history, if there's this much platform incongruity now, should we trust them to change that with time? If you were forced to place a bet, which service provider would you stake it on?
I've nothing against Microsoft, but I think the grandparent poster has a point.
I'm pretty sure I've had the opposite thing happen with Dropbox: files silently not syncing to my Windows machine until I corrected a filename on the Linux file. Definitely not a showstopper but the lack of a visible error message was annoying.
