The USB, PS/2, and KVM problem, and some solutions
I noticed that recent keyboards and mice seem to be moving towards a native USB interface, with USB-to-PS/2 adaptors included. However, after trying out some of the latest keyboards and mice, combined with the latest KVM switches from Avocent and Belkin, I also noticed that this combination often fails. Believe me, I’ve tried pretty many keyboard, mouse and KVM combinations.
I discussed this with a very helpful technician at KVM Switches Online, and came up with the following solutions, for home (2 computers):

and work(3 or 4 computers): http://www.kvm-switches-online.com/4svpua10-001.html
These Avocent products basically allow me to purchase a better keyboard or mouse in the future, yet still have it work. I use an Avocent SwitchView at work (PS/2 only), and it is the best one yet: smooth and fast, without any glitches. So the brand seems trustworthy, at least, so far.
