With the power of our community; Dropbox would have an offer it can't refuse.
although saying that the petition for Windows Mobile stands at 43182 votes and we haven't seen that yet.
Nothing. I just prefer the native from Dropbox. For example, Dropbox client on my Torch lets me browser and view images on the fly, whereas BlueBox I have to "Download & View". There might be more that I dont know of.
I'm hoping a made-by-Dropbox Dropbox app will support active syncing (compared to BlueBox that requires you to download the files you want to view). Either way, voted!
