you've three choices. linux, mac, or windows. windows is an easy operating system on the plus side, but it's a frequent victem of viruses and malware and has lots of drm. macs are safer and very pretty. they are also very very expensive. linux isn't as easy to learn as windows although it's getting easier. it's cheap (as in free) and loadable on any windows box and can revitalize an older computer. you can also go with the double operating system. that's buy a windows box and put a linux partition in it. some apples come with windows capacity. i don't know about linux/apple.
