I like to operate my computer from my bed and so a cordless keyboard and mouse were necessary. After shopping around a bit I decided on the reliable brand of logitech. Both of the items are nice looking, high qulity and so far have lasted me 3 years. However, the keyboard sometimes does work and I have tomove it closer to the sensor and then more it back for it to work,. However the range of button on the top - a mouse scroller, a zoom button, a sleep button, a volume button and pause/play/stop/fast forward/rewind buttons - more than make up for this. The mouse is something I am particuarly impressed with. Just below the scrolling wheel is a button, which when you press allows you to superspeed to the bottom of long pages with just one scroll. Unfortunately, due to the age of the mouse this does sometimes get stuck on, but for the last 3 years it has served me well.
