For over 10 years, I've been using a a Microsoft Wireless Comfort 5050 keyboard and Mouse. It has served me well for my job (3D artist). For the last 2 months it's been going on the fritz, keys not registering properly, mouse pointer jumping around. I have to keep moving the keyboard around in order for the keys to register. When it does register there seems to be a delay. So I was wondering if there are any keyboard and mouse out there similar to it. The function I especially love is being able to map folders to the favorite buttons. So does anyone have any recommendations?
