Been out of commission for a little bit. Do not think much about our winters up here. One handicap has been lack of a functional keyboard. Just tried a Logitech wireless keyboard and mouse combo MK320, they also failed to work! Could it be anything wireless fails? The Logitech mouse is tiny compared to the MS Wireless Mouse 5000. There is no comparison, the 5000 blue laser technology and the extra back and Forward buttons, the size at least double to the Logitech all nice features. Having large hands with long finger's, the mouse is great its size lets me relax my entire hand, the new keys can be hit with very little effort.
