Hi! I might be picking up the new 2011 MBA 11inch model tomorrow. I hope to use it as my primary device: I'll be using it for tasks like: web surfing. writing essays. email, the regular stuff. My primary device is an acer however since my iPad 2 purchase, the iPad has been my primary device for my tasks (mostly because of the summer holidays and I don't have to write essays!) I'll be giving my acer to a family member who needs a computer! I feel the MBA 11 inch will be just fine as my primary device, the screen is just about right, with a nice resolution and isn't much smaller than the 13 inch. Has anyone got any opinions on the MBA 11 inch for being a primary device? Thanks.
