I never fully understood why my room mate insisted on using a mouse with his laptop. He would almost always have one plugged in.
I am generally stuck on a Windows desktop all day so never really had a chance to use a trackpad on a Windows machine. I recently was given a laptop to use by my client so started trying to use the trackpad like the one on my Mac. Holy crap is that thing horrible. I finally understood why the room mate uses a mouse with his laptop all the time.
It honestly does surprise me just how bad Windows trackpads are!!
