eMac software

I am also looking at installing several freeware on the eMacs that will not be in the Studio. The list is as follows:

iAntivirus (free version)
NeoOffice
GIMP
Inkscape and Wacom Drivers
Scratch
Possibly also Alice
Audacity (and LAME)
TuxPaint
KomPoZer
HandBrake

I am also looking at 2 astronomy software, Stellarium and Celestia. If any of my readers is aware of issues with either or why I might want one over the other feel free to give me a comment.
