Hi all, Sorry for yet another '11" or 13" macbook air' question, of which there are already many posted. After significant deliberation, including multiple trips to the apple store, I eventually elected for an 11" MBA over the 13" model. I also decided to upgrade to 8Gb of RAM, so had to wait for my laptop to be shipped. It arrived yesterday. I really like it, however I am now concerned that I have made the wrong decision. I am primarily struggling with the size of the text, particularly in Mail & Safari. I also think that the display is probably not as good for word processing etc. I also have a 24" iMac, however I intend to do quite a bit of my work (generally work/excel/powerpoint) on my MBA. My dilemma is, do I return my 11" 8gb for a 13" 4gb model? The 11" is a fantastic machine, however I worry that i have bought with my heart (form-factor), rather than my head (practicality). Any comments, experiences or opinions would be welcome. Particularly from anyone who has had a similar experience, or uses an 11" MBA as their main computer or for a lot of word-processing etc. thanks in advance.
