I must add that I don't use a LapTop with my Logic Pro in my music room, and I suppose that plugging a mouse into the LapTop would defeat the portability of it!
There's a mouse in the side pocket of my laptop's bag, and if I'm using it for anything more than web browsing it usually gets plugged in. Portability is a highly overrated feature. You need what you need.
