I’m the increasingly discontent owner of an Hotmail account (don’t laugh, I subscribed back when Hotmail wasn’t owned by Microsoft). Recently, in order to compete with Google on the Web, Hotmail’s interface was overhauled: it now has a “classic” interface, which works reasonably well but is still rather limited, and a supposedly “Full” interface that should make it the equal of sites like Google Apps and Yahoo Mail/Calendar/etc.
