There are a lot of reasons to be interested in mechanical keyboards over rubber-dome models. Much of what I could tell you about rubber-dome keyboards versus mechanical switching has been already said. Rather than reinventing the wheel we’ll reread a classic part of what Dan said about mechanical keyboards:

The big deal about these old keyboards is their lovely, positive key-click. When you use a keyboard that doesn’t have a good positive click, it’s hard to tell when you’ve depressed a key properly. You have to watch the screen to make sure you don’t leave letters out, or you have to really hammer the keyboard, which is not good for your hands.

Most of the mid-priced keyboards these days use some variant of the “rubber dome” switch technology, which gives a definite little popping sensation when the dome buckles, but doesn’t necessarily give you an actual letter at the exact same moment, thanks to uncertain contacts. The old buckling spring tech absolutely positively does give you the letter when you feel the click. These keyboards feel very much like an old IBM Selectric typewriter – there are plenty of these ironclad behemoths still in service, and they may herniate anyone that has to move them but they’re darn nice to type on.

Rubber-dome keyboards are just not as reliable, ergonomic, or fun to use as mechanicals. Though you do have to give up some goofy options for mechanical keyboards, this Adesso keyboard is kind-of goofy as far as mechanicals go.

Most mechanicals are fairly boring and extremely beige. At most you might get a trackpoint or trackball. This is why you have to go with somewhat more modern options if you want something closer to the gaming keyboard experience without the rubber-domes.

Which features does the Adesso Mechanical Gaming Keyboard MKB-135B have over the basic Model M? An integrated, modern clicky Cherry blue switches, powered two-port USB 2.0 hub, windows keys, multimedia controls, replacable keycaps, and audio jacks. If you too dislike the beige style you might also be happy to know this keyboard is a glossy black everywhere but the keycaps. Speaking of which, the key caps are painted with a good ink that doesn’t feel cheap.

Even my Keytronic and Logitech G15’s keycaps have faded over time, but my original Model M hasn’t. However, until this keyboard has been in my possession for a few years I can’t give any kind of definitive answer as to the quality of the ink process on the keycaps.

After yesterday’s non-review of the Tango Pro, I’m happy to say that this keyboard feels great, the throw on the key press is close to Model M perfection and far superior to anything you can buy from Logitech or any of the other major peripheral manufacturers. With the Adesso I’ve played enough RTS and FPS games and had a similar experience to my old Model M, except without the pain of giving up normal gaming keyboard features.

The only real downside for the Adesso compared to the Model M is that the plastic isn’t as solid and for the life of me I can’t figure out how the multimedia keys are supposed to work. Most cars aren’t as solid as the Model M, it is just that the Adesso doesn’t have a metal backing plate and thicker plastic like the Model M so maybe it’ll only last for ten or fifteen years instead of twenty-five.

Buy a Model M if you don’t need the extra features, or if however you don’t like the color beige and enjoy these extra features buy the Adesso. I’m not returning it for anything else.
