Every time I use my gf's Mac I am instantly annoyed by the touchpad. Yeah, it's better than the one on my Thinkpad but there I use the nipple which is faster, more precise and quicker to reach also I can scroll around using a button under my thump + nipple. Mac lacking page-up/page-down keys is annoying if you need to do a lot of scrolling/coming back to keyboard/scrolling.
