These small little handy-dandy devices seem to get more and more popular. Anyone here chipped in for a JetKVM yet? Looks and sounds pretty solid. Are there a lot of you that have aquired a nanoKVM?
OK, I've read the wiki entry but I still don't understand what KVM is, or why it's needed.
The last time I visited a data center - every server rack came with a laptop-esque looking control unit. What problem does KVM comes to solve? What does this invention improve upon a traditional KVM?
