I would like to get your comments on pros and cons on using round robin DNS to load balance web servers that are located in geographical disperse locations?

DNS isn't really designed to handle these kinds of problems, although DNS plus other technologies can. Akamai is really good at this sort of thing, you'll probably be better off working with them, since in all likelihood it'll be cheaper to work with them than to try and roll your own.
