I have recently been in the same situation as Omar, but for different reasons. I don't really think you'll notice much of a difference between the 2010 and 2011 models for the reasons listed.
For me the upgrade will be worth it. I have sold my 2010 ultimate 13" and will be picking up the 2011 13" in a day or two. At the moment the air is my only machine as I am waiting for the new Mac Pro's to come out. I really need more screen real estate as well so I wanted to get a 27" apple moniter. I didn't like the thought of getting the cinema display instead of the thunderbolt display so I got rid of the 2010 air. Most of the work related tasks I use my Mac for are very processor intensive (3D rendering), so the upgrade will help with this. Although I haven't been able to do much work related tasks recently since the air has been my only machine for the past three months and will likely be the same for the next three months. However I did buy the air to play around on and browse the internet rather than working on.
So unless you need thunderbolt, and want a backlit keyboard I don't really think you need to upgrade because it doesn't seem like you are maxing out your processor with the tasks you listed. However I haven't actually used the 2011 model yet so my opinions probably not that valid.
