Desktops - Windows, Linux and MacOs

The coming Microsoft Windows Vista and the Apple's migration to Intel has put a lot of people talking about the Desktop OS for a long time.

Here is my 5 cents:

People are used to Windows, and you can't beat that. People are averse to change. If chaging currencies from escudos to euros would never work if people were not obligated, imagine what the learning curve is for someone using Windows to migrate to Linux!

And I also speak for me! Working with a different Linux distro (switching from Suse to Fedora Core 4 has somehow put the sweats on me...

As much as I like to explore new things, I just can't find the time to switch. I will only do so when I really have...

People will on change when the companies want to switch. But you cant't expect that big companies (the ones that really matter for this case) will want to switch. No CTO will put his neck out that much...

Linux and MacOS will continue to exist in the desktop, beeing used only by tecno freaks fringes.
