Hi! Frns,
Microsoft has just launched Outlook.com, and somehow killing the hotmail.com
Its basically a more integrated service for ppl using many services and is also linked with windows live account. It allows users to add facebook, linkedin, twitter, etc. Also not to forget skydrive and office support in it.
The layout(an easy guess) is obviously adapted from Metro/win8. It also lets users have pop/imap account on it.
Well, not sure if its gonna be hit or not, but if in case it gets hit...just signup ur fav id before anyone gets it...;-)
