As innovative and ingenius as it is, the trackpad is, frankly, tiring to use. I feel my hands straining, especially at the wrist. Also, whenever your fingers get sweaty, the trackpad becomes virtually unusable. However, after using the Magic Mouse, I'd say this is still the better choice... but ultimately, nothing beats a legitimate [Logitech] mouse. Maybe it takes some time to get used to...? Am I the only one feeling strain?
