Now don't get me started with SugarSync
Why not? Any complain about it? Any problem that I should be aware of?
not really... as long as you don't use their iPhone app. Okay to be clear: yes they offer 5GB of free space vs only 2 for DB, yes they have a nice Windows interface while DB has basically no client interface at all, yes they allow the syncing of any folder etc... oh and yes their new browser interface is nice...
but their network, if I refer to my experience and to a few articles that confirm that, is a disaster: it's very slow, like 3 times slower than dropbox (download). Also, I mentioned their iPhone app: lol it looks really cool, full of features etc... that the DB app doesn't have, but: it just doesn't work. Stuff doesn't sync properly at all, either not at all or at such a speed that you wanna give up very quickly, which is what I've done. And I tried several times... getting error messages, dropped syncing etc...
Now on the other hand, you may have a good experience of SugarSync if you sync between two desktops... I haven't tried yet but one thing is sure: their download speed is awful. It maxes at 200 KB/s while DB maxes at 600 KB/s. Yeah 600 isn't that fast either, but that's still 3 times faster than SugarSync. Also, I heard SugarSync offered a restricted bandwidth for the free version
edit: just wanted to add, let alone the recent (an really bad) incidents with DropBox, what makes it popular is its simplicity, and its reliability. DropBox network is always "ON" and rather fast.
