Google Desktop

Once while surfing I came across another Google's product. "Google Desktop" Just thought of downloading wow....it simply rooocks. It took me nearly 4 hours on AMD64 Athlon with 512 MB RAM for its indexing. But then it gives results as you type the word just like Winamp media center. Like grep command it scans the documents also which has text material in it. I am yet to find out how much memory it eats but as far as my messy comp is concern Google Desktop has really made me lazy. hehe
