This certainly causes this chip the fall from the graces of being "easiest" since it pretty much requires a PCB to be made. Since much of my prototyping is done before a PCB every gets made this makes it a difficult choice. Ignoring that, FTDI is pretty good. I have one of their 32pin TQFP parts on a board here, an FT245. It was a breeze to get working. Simply followed the datasheet with regards to layout and support circuitry. Soldered it down, plugged it into my linux box, started up minicom and it was working. Couldn't have been easier. Windows was only slightly "harder" since I actually had to download the driver (linux has it built in).
