They should get a mini transmitter/receiver like Logitech. That works great for laptops as you can just leave it there and it almost never catches on things.
I agree, Logitech's receiver is the best invention since the optical mouse! And why do these things always cost $100 then 3 years later sell for $25-$30? Greedy bastards! Maybe it's just cause of their longevity, my primary mouse is still an MX500, best mouse in the world and it's gotta be nearly 8 years old.
I had a MS wireless keyboard and mouse and hated the keyboard (el cheapo). I got a Logitech wireless one and have been using it for years, even for gaming. I have a mouse pad with wrist rest. So, I will be sticking with Logitech.
