Does the Lack of Vertical Screen Real-Estate on the 11" Macbook Air Hinder the Ability to Write Papers?

Hi,

I currently have a 2011 iMac 27" that I absolutely love, but I sold my Windows 7 laptop to afford it. I'm finding myself more and more in need of portability for writing papers. I'm a bit torn between the two size options. I'd love the incredible portability of the 11" but I'm not sure that the size will be enough.

Your thoughts & experiences?

Thanks!
