This is slightly off topic, but I have been creating photo books ( I use iPhoto, but there are other brands out there) of trips we took with our kids and send copies to their grandparents. I've found that electronic media is very easy to lose, and for really important pictures of my family, it it's nice having the books "off site". I figure these books will survive whatever changes occur to standards in electronic formats.
On topic, whenever someone purchases an Apple computer, I strongly recommend getting a Time Capsule. Easy to install, hourly backups.
