You must rmember that we are now paying Apple a premium price for a Windows computer that will also boot & run the Mac OS. It is not the other way around. This means that many of us loyal Mac Users must also use the Windows computer as it was designed, i.e. with the Windows OS.
You may be one that can live without Windows. Good for you. If I would get around to writing my own efile program for doing income taxes I could probably join you, but until then I need to run Windows on a daily schedule.
If we can get our copy of Windows for $29 all the better. Most of the time that I am a student I can get the Windows OS for free or a few $'s for a disk.
I still have only computers sold to me by Apple. It is just that the new one will do a good job of running Windows. So if Apple built it, it needs to be used for everything that it can do. That means that the Windows OS is included in that.
I have no idea why you can't do your taxes on Mac OS X? Last time I checked Tax Cut and Turbo Tax were both on OS X. I used Turbo Tax to do my taxes this year and no issues whatsoever with e-File. I didn't need Windows to do anything. When people like you make statements like this you are spreading FUD and most likely are just making excuses to use Windows when you really don't have to.
