Hello! I have a MacBook Pro that I have faithfully used for the past year, but I need a more mobile solution and until Apple releases their ultraportable, a MacBook will have to suffice. So I picked it up today, and both the keyboard and trackpad have very sporadic "misses". The right side of the keyboard (enter, delete, etc...) sometimes does not register keypresses. Surely this isn't normal behavior? Also, the trackpad is very very insensitive most of the times, and then over-sensitive randomly. I have unchecked the option to "ignore accidental trackpad input" and it still persists. Should I take the laptop back to the Apple store and exchange it? Help!
