I have been using the newer version of GMail for the last few days and I like it very much. The first thing I noticed is that it's faster than the older version. But the feature that I liked most is the Filter Messages like these action. Its wonderful and is saving me so many more minutes everyday. The other new action Mute takes out the message from my inbox, but I am not sure whether it archives it or deletes it do what with it. The replies by you are marked with a > sign in a discussion thread to easily distinguish between your responses vs the others responses. And of course the Contacts section has changed significantly in terms of visual appearance compared to other parts of the GMail. The embedded google talk now gives optionto show the list of contacts to chat in different sizes - tiny, small, medium, large.
MicroSoft made its Windows Live Hotmail available for general registration. I tool my new live id email@example.com . At first look, I think the calendar, calendar sharing and task integration in it will be useful. They are giving 5 GB space to start with which is cool. Let's see how it goes.
