Microsoft completely rebuilt Windows Phone 7 from the ground up. The Start screen now features live tiles that provide one-touch access to your favorite apps and contacts. They also alert you to new messages and calls and status updates.
A quick swipe to the right from the Start screen brings you to a full list of your apps. We're not huge fans of this long vertical list, as it requires a lot of scrolling. As you add more apps, we can only imagine it will get more unruly.
A large part of Windows Phone 7 is centered around Hubs, which brings together related content into one central zone. Here you have the People hub, where you can find all your contacts, see their status updates, and more.
The Windows Phone 7 preview device we received from Microsoft is called the Samsung Taylor. It will never be released to market, but will be offered to developers prelaunch so they can test their apps and meet all the platform hardware requirements, including the three requisite navigation buttons. Smartphones from LG will also be distributed to developers.
Here is the landscape keyboard. When you're entering a URL or e-mail address into a To field, the keyboard automatically brings up a .com shortcut. Similarly, when you're writing a message, it surfaces a shortcut to a list of emoticons.
The Office hub allows you to view, edit, and create Word and Excel documents, as well as view and edit PowerPoint presentations. However, the editing options are pretty light, and there's no copy/paste.
