Right now I have my 15" MBP on a stand on the workstation and use an Apple BT Magic Keyboard and also the Magic Mouse II with it, so don't use the trackpad. With my 12" MacBook, if I'm using it on a table or desk, then I prefer to have the mouse, but sometimes that machine and I do get into situations where there is no other place besides my lap to use the machine, and so I do use the trackpad then. I'm awkward with it though, since I don't use the trackpad enough to remember all the gestures and such.
