For me personally, Dropbox is the way to go. I use it for this same purpose all the time - quick file transfers between my phone and my computer. That said, this is definitely for the person who a: doesn't want anything to do with a 3rd party service, and b: wants to completely manage their files/folders on their Android phone from their computer, or drop files in different folders on their phone, neither of which Dropbox lets us do.
Point taken through, there are other apps that do similar things. Options are good.
