Which keyboard and mouse should I buy for my PC?

Mamie would like to replace her old keyboard and mouse with something better. There are plenty of options ...

My Dell desktop's wired optical mouse and keyboard are getting a little long in the tooth, and I'd like to replace them. What do you recommend? Are wireless devices worth it, or do you continually need to recharge them and replace endless batteries? I can touch-type, but my skills are a little rusty. Mamie

Keyboards are partly a matter of taste, and habitual use overcomes many objections. In other words, if you use a flawed keyboard for long enough, you'll get used to it. You may even come to like it.
