This is exactly what Microsoft is doing - intergration. Windows Explorer and Internet Explorer, intergrated. Internet Explorer is built into their system to not give Firefox ect. a chance. Windows Media Player, not giving RealPlayer or Quicktime a chance.
Apple is bundling Dashboard into their OS to give Konfabulator no chance. They do that with Quicktime, and Safari, but in a different way - Finder and Safari are not intergrated, so you can use whatever browser, and you can not use Safari. That's why Microsoft is in so much legal heat.
Apple, I think you have dissapointed a lot of people.
