| I just got a new 12" Powerbook (YAY!) and it came with 5 GB already used up on the hard disk. Does Mac OS X and iLife really take up 5GB? or is there something I dont know? |

I just brought you also about a week or two ago... congratulations you love it I love mine. Ilife takes up alot of space. If you dont need all those Ilife apps you can delete the ones you dont use. I removed Garageband and Imovie. That will clear up some space.

| In my experience the GBs vary. Mine is supposed to have 120GB but in reality has around 115. On the other hand, sometimes you get more gigs than you thought. My IT friend scanned it for me to see what it actually was...I don't know how you do that, tho. |

I'd add about 10% of your internal HD capacity to that overhead, for elbow room once you drive fills, and you have, effectively, 68 GB available. If, down the road, you need more storage, FW drives are relatively inexpensive these days and available in capacities up to one TB (1000 GB).

One other thing to consider. A gigabyte is 1,073,741,824 bytes (1024 cubed) but most drive makers now are advertising "100 GB" when the capacity is 1,000,000,000 bytes. So you're seven percent short before you start formatting.

| Plus you need to allow for the boot sector. |

You should read this:

To understand one of the two issues.
The other is filesystem overhead, which for a modern drive is pretty considerable. Think about how much space it must take to be able to have an index to the billions of pieces of data stored there so you can actually find things.
Formerlee: the boot sector space compared to a 80GB hard disk is completely negligible. There's a reason it's called a sector, which is a subsection measurement of space on binary storage media. In the context of a modern era PC, typically that means 512 bytes. If that was the only discrepency I most people would ever notice it.
