My biggest complaint is the %$#@$I% button/trackpad. First of all, it only registers maybe 60% of my clicks. Sometimes I have to take my fingers completely off for a second, then click for it to register it. 2nd, I cannot click it with just a finger motion, I have to use lots of force from my hand/arm to click the dang thing. It seriously takes me to move my entire hand to click it, i cant just push my thumb a little to click it like the previous buttons. 3rd, It is the loudest click I think I have ever heard. Painfully loud. Am I alone here? Otherwise, love the computer/design and whatnot, i just need to get this mouse clicking thing figured out or Im going to be very frustrated.
