Microsoft's Hotmail email service has been a good and reliable email service. But over the years it interface become a reminder of the cluttered old web interfaces of the past. The last update to Hotmail tried to correct this, but it did not work out too well.
But little by little, the new Microsoft Metro interface which first made its appearance in Windows phones and is now moving over to tablets and personal computers is also making its way to Microsoft web services.
I do not think anyone is going to complain about Metro on the web. I has a Google like minimalist feel to it.
If you already have a Hotmail or Windows Live account, you do not need to sign up for a new address to use the new interface. Just go to the setting menu and select upgrade to outlook. You can also get a new @outlook email address. Your older email address will continue to be active unless you decide to deactivate it yourself, and you can get email from both addresses in the same Inbox or separate folders.
Lets hope SkyDrive gets the same Metro Treatment soon.
