Oops, MCSE does not really exist anymore. Microsoft's new certification lines are "MCTS" and "MCITP". And if those are a joke (the TS line is pretty easy -- ITP somewhat more challenging), then I'm sure the Linux certs, in whatever form they come, are equally useless or useful in determining your level of knowledge. Hell, even someone with 5+ years of "work experience" may be a complete joke... but you've got to go on SOMETHING, right?

Dell has actually had "brick and mortar" kiosks inside airports for a couple years now. Their salesmen are always dressed in blue Dell polo shirts and khaki pants. The kiosks seem to get a lot of foot traffic, but I have no idea what kind of sales they bring in. I imagine if Dell opens up inside another retail store, they'll probably opt for the same type of setup.
