Writing this on a MAC

So my MacBook Pro came today. I was worried that I would miss the UPS man. I had a flight to Huntsville, Alabama and back that arrived at 1:40PM. The UPS man normally brings stuff around 2PM or 6PM. I rushed home and was here about 10 minutes before he came. So far I see a nice big learning curve ahead. I gotta figure if its possible to click using just the touchpad and not the mouse button. The keyboard is also different. I used the home, end, pgup and pgdown keys alot. All are gone. This will be fun...and I am sure frustrating.
