I have to rethink my setups pretty soon. For the most part I do plugin development. The desktop is dual screen 64 bit, the laptop is 32 bit, but with SSD.
I prefer working on the dual screen but the 64bit interferes with Edit and Continue. The laptop is speedy, and allows Edit and Continue, but feels so damn claustrophobic.
Visual Studio 2013 would certainly solve one problem: I suppose a Surface Pro with a dual monitor dock could solve the other.
