Hi,
I jus wanna know that wat is the difference between apple Pc and other pcs,apple's architecture and why machintosh does not install in windows...

Hello

Apple is totally a different system than Microsoft Windows founded by Steve Jobs.
Apple's Leopard is assumed to be the most advanced OS of the world and what Vista contains now ( i.e superfetcher, automatic de fragmentation, Opera feature,Mac look like), Mac had lot of time before.

In Dev language, we can say , MAC is a wrapper over Unix ( i.e made on Unix).

Quality of work, images, ability to tweak, viewer are great in Mac

Its true that MAC OS cannot be installed on any Dell or IBM PC. But windows can be installed on MAC machine (i.e Apple H/W) after formatting the Machintosh OS. (compatible)

Mac could have dominated the whole world as does Windows do now if
1) Mac had not made the policy that MAc OS can be only installed on hardware produced by Apple. (Mac does not provide compatibility)
2) Steve Jobs would not have been thrown out of company for some years

I really love working on it and mail me back for any details .
