In addition to establishing these minimum specifi cations, Microsoft has stated that certain features
will not be allowed on devices branded as Windows Phone 7. Currently, that list of prohibited
features includes removable memory (via microSD or any other format) and having any extraneous
buttons on the face of the phone beyond the Back, Start, and Search buttons.
Chassis Design
One of the truly great things about Windows Phone 7 is the consistency of chassis design between
manufacturers. This will likely change with future generations, but all the devices available at
launch sport the same basic form factor. And, thanks to Microsoft’s involvement, all devices also
have a roughly identical feature set, as shown in Figure 1-1.
