In those apps hyperthreading helps, but it's not that big of a performance increase. Perhaps 10% performance increase for a lot more money. In a device like the surface pro, that shouldn't be a deal breaker. Just being able to run that workload on a tablet form factor device is amazing and surface pro 2 should run it pretty well even without the i7. If you make a living working in those kind of apps then I think a surface pro 2 should probably supplement a very powerful desktop.
