Well you have Microsoft Office 2004 for mac
This may sound off topic, but there is an interesting fact abt IE for mac.
IE 6 for PC till date i.e. 2005 doesnot render transparent PNGs properly. I think my graphics friends here will confirm that.
However, IE 5 for mac renders these PNGs perfectly since 1999
The "no-software" thing for mac is completely BS. I said it before.. i'll say it again.. 5 good software are better than 42343242 bad, ugly and cheap ones.
And oh btw check versiontracker.com for freeware for mac
Also most linux apps can be ported to mac with fink
