Best Ways to Share Files With a Nearby Computer

"[W]hen you're trying to share files with someone in the same physical space as you, it hardly seems necessary to go through the slow process of uploading files to and downloading files from the internet, especially if they're rather large files. There's always the tried-and-true method of dumping your file(s) on a USB thumb drive, but if you don't have one handy (or you don't have a big enough drive), you've still got options...."

The article touches upon setting up file sharing under MAC and Windows 7, and then discusses transferring via Wifi (including using an Ad Hoc wireless connection), FireWire, and Ethernet (for which you may or may not need either a cross-over cable or adapter. The latter is pictured above, lower center). Of course, there are other alternatives available, including a USB Transfer Cable (upper left above), or via a "LapLink" transfer cable (upper center), although you might have trouble finding serial or parallel ports on many modern computers. Was amused at the thought that the "tried-and-true method" of local file transfers has become via a USB drive, whereas the "sneakernet" that many of us remember involved floppies (and 5 1/4" floppies, at that!). USB has the advantage of being nearly ubiquitous: does that make it the best choice?  What is your favorite method of transferring files from one system to another (especially if away from your home or business network)?
