The Macbook Air and the Macbook Pro are both known for their best in class touch pad. Accurate and smooth to the touch, nothing really compares. Love your Macbook touch pad? Find even more reasons to love it and pick up a stylus, for tablet style pen input on your Mac.A little known fact about the Macbook touch pad is that it uses similar capacitive touch detection to the iPad and iPhone. This means that any stylus meant for use with the iPad or any capacitive tablet can easily turn your Macbook touch pad into a small, but effective drawing tablet. I was able to pick up a capacitive stylus from the local dollar store for cheap, but most computer stores offer decent rubber tipped stylus at an affordable price.
