Copernic: A search monster

I was not using any third party desktop search engines. Mostly beacause, I had a really slow computer, and the windows search(which I was used to) did the job. After getting my new desktop, my friend(Kris) recommended the msn desktop search. So I went ahead, still being really skeptic, and installed it on my system. Soon my life, and finding things on my desktop became so much easier. It became a lot faster too, blink of an eye faster. it was the best thing I installed on the system. Especially with all the songs, and musicvideos, you need something like this. But then, I guess I hit the trying out new things "phase". So, I removed the MSN desktop search, and upon the recommendation of Ajith, I installed the Copernic Desktop Search. this was even amazing, the interface, the quickness, the side preview things. It was nice and fancy. But you see all this comes witha price. You need to have a powereful PC, prolly a 1gb ram, is nice to have. It will work with 512 too. These search engines are fast beacause they keep indexing your computer, while you are sleeping. And thus the quickness. All I can say is, try out these search engines, and you'll be amazed. Both 'em are free.
Also, I recently went to Copernic Site and it's search interface and M$ new OS had some similarities, with the previews and rating system and all that. But thats just me.
