Hotmail App For Kindle Fire Arrives, For Those Clinging to The 1990s

Microsoft has just released a free Hotmail app to the Amazon Appstore, claiming to have optimized its existing Android app for the Fire. No doubt it probably works better that the Fires's native email client, which is tolerable at best. What I want to know, though, is who the hell is still using Hotmail? What is this, 1998?
