The latest update means that I can even access the whole file system on the phone from Windows without plugging it in. It can be in my pocket or setting on the wireless Qi charger on my desk. What's amazing about this is that this integration happens deep within the Windows file system, so whether it's connected via USB cable or wirelessly via Phone Link, even old third-party apps that don't support the modern file UI can read and write directly to the Android device like it's a flash drive. This means apps to edit documents and programs that copy files (needed for syncing music since MS abandoned OneDrive and Zune/Groove music support) work seamlessly over this. Obviously, it's faster for large transfers when connected via USB, but if not moving many GB of files, the convenience of not having to involve wires is a huge win. And the wireless connection performance is surprisingly good.
