Mid-length straight hair, for everyday use

I have finally decided to get a Dyson hairdryer/styler. I don't have the budget to invest in both, so I was wondering which would be better. I already have a hair dryer but the faster drying time of the Supersonic is very attractive. But at the same time, I'm thinking, is it worth the extra money when I'm essentially buying another hair dryer? Are there any cons to the Airwrap? Help me decide!
