Hi William. Yes, wireless keyboard and mouse is a very good feature.
The wireless optical mouse of course, needs to have a surface to sit on, that has a bit of a pattern for the optical sensor to detect. I had a glass surface protector on my desk, so the optical sensor did not like that. I just put down a blank piece of 8 X 11 sheet paper and the optical mouse works fine.
My wireless keyboard is a bit smaller than a standard full size keyboard and that is great for me, since it frees up more of the desk space, for use.
