Yahoo Messenger Latest version is 5.0 + I say it is good but, not the best. Yahoo Messenger new version offers some utilities like screensavers while chatting, what is the use ? We want fast, reliable service which I have to say MSN Messenger offers the best. Their service is the best, the fastest, and the most user friendly.
I would suggest people to switch over to MSN and try chatting on that and I am sure you will enjoy it. Yahoo’s Voice and Video chat is also not upto mark. MSN voice and video is perfect and it works the best even if you have a dial up modem. Yahoo voice and chat works only if you have a dsl or a isdn connection.
To sum it up, use MSN, if not satisfied ( which is rare ) then switch over to Yahoo. As for the latest version, you should download it, as it is free.
