I think it’s worth it to take the time and look for a really good keyboard. Some might say only a pedant would care about details like the amount of pressure to hit a key or the sound it makes, but it really can make a difference if you do a lot of typing.
For the longest time I used whatever keyboard came with the computer (Dell’s and HPs), and before that I used random spare keyboards from my dad’s computers. A few years ago I finally went out and bought an expensive keyboard from Razer called the Lycosa. I remember being pretty happy with it for awhile but after a few years of use and a bunch of crap being dropped between the keys I finally decided to get a new one today. I saw recommendations of the Das Keyboard, but without actually typing on it I wouldn’t consider it. There were also recommendations for one of the old IBM keyboards which I have used before, but I didn’t feel like special ordering something and I wanted my fingers to just glide of the keys and not have to put much pressure on them.
I actually found one I really like and ended up purchasing at Best Buy (oh no!). It’s terrible I know, but I enjoy going there with my fiance and walking around. Anyways, I ended up getting a Logitech Illuminated Keyboard. The moment I put my hands on it I knew I would be buying it. It’s got a great feel to the keys and I like the slim profile. I would definitely recommend checking on out; they should be available at any major electronics retailer.
