Bad news for all you Apple Mac OS fans. Mac OS 10.5 code named “Leopard” is going to be introduced to the market later than sooner. The reason? Windows Vista. Not that Windows Vista is setting anything on fire these days as all Vista does is exhausting even the best computers’ resources and slowing PCs down. However, Apple’s Mac OS comes with a little magic software called BootCamp that allows Windows Fanatics to run Vista on their Macs as a second option to Mac OS. Boot Camp is currently in Public Beta phase, and it is fully compatible with Windows XP. However, it is not fully compatible with Windows Vista and its drivers. So, Apple is supposedly delaying its major OS to ensure full compatibility with Vista? The reason? If BootCamp becomes fully compatible with Vista, then there is no need to buy a PC anymore. You can buy a Mac, and install Vista on it, and you end up getting a better system after all. Not only you will get Vista, but you get what is exclusive to Mac owners, Mac OS. Are the days for PCs numbered?
