iOS 5 vs. Android 2.3 Gingerbread vs. Windows Phone 7 Mango vs. Blackberry 7 OS

I'm planning on getting the Atrix this Sunday but I didn't know Android doesn't have tabbed browsing or Rich Text Emails. Anyone know if Honeycomb will or another udpate?

I also have to admit that it sounds like Windows Phone (Mango) is getting a lot better. I'm very interested in this down the road. I'm currently a BlackBerry user and feel the others are blazing past RIM as they sit around and do nothing. Which is why I'm looking to go to an Android device soon this weekend! But looking this chart over, it seems Android should consider some of these updates if they haven't already.
