For me, this is better
I have a feature on my work line that will ring my mobile phone at the same time as my desk phone, and this is a great feature as I can turn it off when I am on vacation and I do not have to give out my mobile number. For my personal needs, I have a Windows Phone as it has Zune and xbox games. For work purposes I have Office on the phone and it connects to the exchange server. You can take this phone from me over your dead body.
