Thinking of switching to Windows Vista?

as most of you know, Microsoft has just released Windows Vista. It's the new version of Windows and they claim that it's more advanced than Windows XP. But wait.. most Windows Vista features are already present in Mac OS X! Aero UI is just a copy of Mac OS X Aqua UI which was already present 5 years ago! Windows Flip 3D is also a copy of Mac OS X Tiger (10.5)'s Expose! Microsoft is claiming that Windows Vista is the most secured OS of this time.. then why would MacOS X, in 5 years of existence didn't have any viruses, spywares, trojans, etc ? And upgrading to Windows Vista would require you to buy a new PC, bec of it's system requirements! So still thinking of getting Windows Vista? Get a Mac instead! :P
