Okay. Well... I should probably put in a word for Macs :-)

1) You don't have to worry about viruses. It is a matter of controversy whether macs have *never* gotten viruses, but everyone who I know who has a mac doesn't have virus protection and they have never gotten hit.

2) Good quality components and a solid design. Other computers can have variable quality on the components (cheap stuff made in china or wherever). Macs are fairly solidly American products, and what is delegated out is quality controlled fairly well.

3) Great for music / photo / video kind of stuff if you are into doing (making) that kind of thing.

4) Doesn't get so cluttered with crap. While microsoft will put little backups and splatter temp folders everywhere where you can't possibly find them to delete them macs simply don't seem to do this.

5) Your system will ask you if you really do want to download that thing from the internet or if you really do want to run that program that you have downloaded from the internet. You have to put in an admin password to do that. That is better security, basically. You don't accidentally download stuff and your computer doesn't do that without getting your permission in the form of an admin password.

6) Time machine backups (external harddrive required) are a BRILLIANT and NO FUSS way of saving the total state of your system incase you do get the dreaded crash. You can even search through your desktop (and directories) as they were at past points in time. Easy to find stuff you accidentally deleted! I do a time machine backup every night and it is really very simple to do.

7) While it takes a little bit to get used to Leopard compared with Windows once you get the hang of it it really does seem a whole heap simpler, more intuitive, and cleaner (less junky). But that being said you can run windows on macs these days if you really really really really want to (though I don't know why anyone would).

8) Less updates. I think this is mostly a function of not having to worry about virus protection. With my last system updates would come through every second day or so. Now... I have a lot less updates coming through. That is good, I think, because updating is a pain in the butt.

9) System is more stable (better designed). Less crashing and freezing up.

10) Nice features / design. Magsafe adaptor that is magnetic and will simply disconnect if you trip over it rather than crashing your computer to the floor (with respect to laptops). Nice number of ports all tidily tucked away on one side of the computer rather than distributed all over. Nice feel keyboard (firm touch and not too 'clacky'. Cool features on the touch pad (can set it up to do right click and two finger scrolling through documents).
