o You don't need to drag around a USB cable. The PNY comes with an extension cable, but you don't need it; this plugs directly into a computer... and its baby cord squeezes between the other USB plugs.
o This is much more portable than pretty much any other reader I've seen. If you plan to leave your reader on your desk connected to one computer, then the other guys are just fine. But this fits easily into pants or shirt pockets -- and again, there aren't any cords to lug around (and leave behind).
o I haven't had any of the hassle another reviewer mentions.
