SugarSync is a great tool for file backup and synchronization. Good speed,  multiple computers, 80$ for 60Gb per year. Great.

It has its bugs, like the stupid method of "let’s check for a timestamp and upload the file again, before checking for size".

And there is one feature I would like: iPhone Camera Roll sync with my computer. DropBox has a similar thing, but not automatic. iCloud does it automatically. I am not expecting to do that, but I would like to sync my Camera Roll photos when I open the app.
