Query: Works fine, no problems, very stable

I've had it for about six months -- works as advertised, plugs in and zoom -- no problems.Minor issues: 1) The power adapter takes up 3 slots on a regular power strip. Why can't manufacturers design AC adapters that take up less space, or just put a short extension cord between the adapter and the outlet? 2) If you have an older (pre-2.0) USB device, functionality of all four ports will drop to that level when the older device is plugged in. Not a problem, as long as you know about it.Addendum, 14 months later: ...and for even more good news, it's extremely stable. I have a Belkin USB hub on another PC -- cooler design, but the Belkin disconnects itself occasionally. I don't think I've ever had to unplug/replug this D-Link. It's not going to win any design awards (it's a gray box, after all), but who cares? Next time I need one, I'm sticking with D-Link.
