how did i miss this thread :tongue:i have been using this for ~1 year and if you remember, i recommended you to get this from US when your friend was coming over.@usage, you will get used to it in few days(10-15 at max) and then its really comfortable.@build quality, i am not sure whats wrong with yours, mine is fine. Of course, because of the trackball, you might think this thing is not solid, but its not going anywhere soon. Also the trackball comes off(for cleaning purposes) and that's why it feels sorta shaky.will post cons a lil later
