What companies? Just look at the pictures in the article. They look great. This is my honest opinion.

I quickly looked over the new Outlook.com service and I must say I'm quite impressed. Everything is clear, there's folders (which are completely lacking from Gmail!), it works fast and the UI looks great.

Outlook.com is also an great domain name and easy to remember. The Facebook and Twitter integration works great and the whole thing feels just superb. I can't but recommend you to try it!
