When I got my Windows computer last autumn, I needed a keyboard and mouse to got with it. I opted for wireless units for both. On the plus side, they work well and they glow in pretty colours. However, I think I could do with a slightly larger keyboard including a number pad. The most inconvenient thing though is due to their very nature: wireless items need charging.
I could probably get 2-3 days regular use out of the keyboard and more from the mouse. However, since you don’t get much warning before the device stops working, I’ve got into the habit of charging them up ever evening. This is workable but does get annoying. At some point, I think I might switch back to wired equivalents… although I still want ones that glow with pretty colours.
