Just bought a new macbook pro 15' after owning a few pc laptops for a while. So far so good and I'm enjoying my somewhat costly purchase. I can't however get used to the new trackpad. The button feels really heavy, clicking with the trackpad takes quite a lot of effort and makes a loud clicking noise. Tapping instead of clicking seems to take just a little bit of time to register and sometimes doesn't. While I would never go back to my hp laptop and it's trackpad it seemed more responsive and the soft trackpad buttons more useful. I could click on both buttons to close a firefox tab for example. My questions are: Is there anyway to make the tapping more sensitive. IE barely touch the trackpad to click? Is it a good idea to loosen the screw to make the trackpad button more responsive and easier to click on? Finally: Any recommendations for a mouse for everyday use? Preferable with an extra button that I can associate with the "back" button for firefox. Thanks !
