Mabye so, but you still have to look at this. Microsoft claims to have the best programmers and designers in the world, why cn they not make something work in a Macintosh environment, which they have always been able to do in the past?
That is how Microsoft does things when something begins to become threatening, like Netscape in the past and now Mac OS X. Instead of continuing to embrace this part of the market, which they have done with Office for Mac for the past several years, they are going to try to kill it, slowly at first so it doesn't look deliberate and they will come up with all kinds of excuses to make it SOUND legitimate. They learned a lesson from attacking Netscape like they did: Do not be overly aggressive and say you are deliberately killing a competitor to protect your Operating System, (when it did not allow manufacturers the right to pre-install Netscape Navigator on Windows machines at the factory.)
Microsoft is attempting maintain a monopoly on the market, a bit Apple has been chewing at for a little time now. Notice how Microsoft continues to mimic Apple and Sony innovation, with the release of the Xbox, (response to Playstation,) and their new portable MP3 player, (a response to iPod.) Windows Vista is a direct rip-off of many features of OS X, many things that could not come up with themselves.
