read phone state and identity permission-OK?

[tenchy]

I don't like the way some apps desire what I consider unnecessary permissions for what they do.

For example, why on earth does AccuWeather need this permission:

Services that cost you money
send SMS messages
Allows the app to send SMS messages. Malicious apps may cost you money by sending messages without your confirmation.
directly call phone numbers
Allows the app to call phone numbers without your intervention. Malicious apps may cause unexpected calls on your phone bill. Note that this doesn't allow the app to call emergency numbers.

Anyway, what are the security implications of allowing this one:

read phone state and identity
Allows the app to access the phone features of the device. An app with this permission can determine the phone number and serial number of this phone, whether a call is active, the number that call is connected to and the like.
