Mac OS Tiger Vs Windows Vista

Today I noticed some of the great features that Mac OS Tiger provides at www.apple.com. Seems like Mac OS Tiger has most of the features that has been implemented in Windows Vista. Who implemented it first? I'm not pretty sure about that, anyway this is just a small attempt (just about two features that I was impressed) to appreciate what both operating systems have done. The searching feature which shows the search result as you type-in is really useful to find files and programs so quickly rather than waiting for the complete search result. Widgets (in Mac) and gadgets (in Vista) are really useful light weight applications which provides different kinds of information monitoring features. I think these are really nice features which helps users to make their life easier.
