Yahoo! today launched its Desktop Search in beta. Another major company backing "search" to be the frontier, the company has brought out this desktop search sometime after giants Google and Microsoft have already tasted some success with their own desktop search products.
This offering from Yahoo provides desktop search for videos and MP3 files. Other prominent features include Instant preview of cntent and search filters. Not anything extraordinary from what the competitors have to offer. Probably Yahoo! will have to face the late-mover disadvantage, and come up with something "new".
