I have been using a MS Wireless Laser 7000 & Mouse Combo for a very long time. So long I have purchased 2 others after the key board goes bad. My thought was, get rid of one and just turn the other replacement on. That worked fine for a few years, but I have worn out the keys again and there are no replacements to be got. Tooo mush online gaming with the keyboard. So in the groups opinion, what is the newer model replacement for this unit? Or even another brand. I realize it's all in preference.....but willing to look at all.
