Hate wires? Who doesn't? This is 2011, after all.
Well if you answered the affirmative to that question, funkyFresh might just have the app for you: it's called "Samba Filesharing," and it allows users to access their Android device(s) over WiFi as a Windows shared folder.
With this free app, you can wirelessly copy files to/from your Android device via the same drag-and-drop interface you use when your handset is plugged into your computer with a standard USB cable. Even security freaks have a reason to celebrate - Samba offers customizable username and password options in addition to letting users choose a Windows workgroup name and a device network (NETBIOS) name. It's free, so be sure to give it a download - you know where to find the QR code and Market/AppBrain links.
