I'm going to post software, and describe them, for those who are lazy to google.
wp means word processor

All of them are for macs unless marked.
RMXP(xp) and RMVX(vista)-$60, but is awesome-makes rpg games easily-WINDOWS
VMware-totally needed for macs, but is expensive-runs windows on your mac (or you could use boot camp)
stencylworks-stencyl, a programming... thing..., cross platform, blocks like scratch
thunderbird-cross platform, check mail
chrome-cross platform, browser
fugu-ssh, and all that file stuff.

offshoots-cool desktop application, shows branches that grow
gimp-cross platform
idmg-make dmg files
ishowu-record your screen
picasa-cross platform, like iphoto
abiword-word processor (wp)
bean-wp
cocopad-draw sketches
genius-i think it's flash cards to study

AND the second best app: (behind scratch)
Wine! and wine bottler, they come together. and Trix comes with it too I think.
So you're thinking, well, wine, it's like to view wines and buy them right?
NO! If you're thinking that, you're absolutely wrong.
You can run exe files on mac! You can also make exe files into app files, if you want using wine bottler.

I hope this post has inspired you to download at least one of the softwares above!
