that it dominates the market from A to Z, and thats the bottom line." Triel -- Ask anyone in the Graphics or Music industry what they use. It's not even about PowerPC's anymore. it's just down to the OS. Don't get me wrong though -- I have no desire to see Apple where M$ are now. It would be more of a closed market then what M$ currently offer. Oh, and Name (required) whoever you are...UAC is M$'s way of attempting to remove the user from the Admin account. Apple don't allow the user to be Admin 24/7. Neither does any Linux distro. (See Dell.co.uk for ubuntu on their entry level systems btw.)

I'd like to address a couple of issues. 1) Dialogs don't protect the user unless they already know what they are doing, They either lead to wholesale ignoring even of important ones, as previously discussed, or worse they lead to wholesale panic and fear of using the computer. This is certainly the case for people of my mother's age etc. To address Mathew above. It is a fact that the a large % of home users don't know what they are doing and have no understanding of computers.
