The tiny plug scared me at fist. I was really worried I was going to break it, but I've been plugging and unplugging my N800 constantly for a little over a year now. There are no ill effects and the fit doesn't seem any looser than the day I bought it.

I'm pretty sure the power jack/socket are specced for more plug/unplug events than a mini-b usb jack/socket, but I could be mistaken. Just because it "feels" more solid doesn't mean it is...
