This isn’t specifically related to Tiger, though I find that it might be of interest for some of you. Being averse to a cluttered desk I decided to buy a KVM switch.
k/v/m stands for keyboard, video and mouse. It’s a small little black box that you plug your VGA (or DVI) monitor cable, your USB keyboard and mouse. Then you connect the box to your Macs. In my case, the PowerMac G5 and the TiBook G4. After that, you may use the same keyboard, mouse & monitor for both computers. By pressing a single button you can switch between the systems, thus using one e.g. for office work while the other one is busy doing movie editing.
I usally keep my TiBook G4 booted in Mac OS 9 now while the G5 workhorse does my everyday work. The Aten CS682-AT I bought wasn’t specifically cheap (50 euros) but it is a quality product and doesn’t show any unreliability as it happens with those 15 euro switches.
I must admit that I’ve become so used to my Aten switch that I could hardly imagine ever doing without it again. It’s great for switching between a gaming and a productivity system or a retro and a modern system. If you haven’t tried it yet but you use two (or more) Macs at the same time, give it a try.
