Google Earth for OS X is coming. Someone posted a link to a beta version a week or two ago. Turns out, it wasn't okay with Google.
So most of us will have to wait.
Here are just a few of my favorites:
Firefox 1.5 (free -- I'm still going back and forth between this and Safari)
VLC (free -- view almost any video file)
MPlayer (free -- some prefer this to VLC -- or use both)
Celestia (free from Sourceforge -- amazing astronomy app)
Mac_DAZStudio (free from
www.daz3d.com -- 3d animation app)
NeoOffice (free port of OpenOffice.Org 1.x - implemented in Aqua)
DoomLegacy (free from Sourceforge, I think -- if you're a retro gamer)
FlightGear (free flight sim, haven't tried it yet, just got it)
Commercial programs:
Photoshop Elements 3
Splinter Cell (if you're a FPS gamer)
Microsoft Office 2004 (try NeoOffice first)
Is this PowerBook one of the newer ones? If so, you have the two-finger horizontal and vertical scroll on the trackpad--very cool! [SIZE=-1][/SIZE]
Have fun.
