Most web sites use a width of around 980px and do not scale the width if more is available. But intranet web sites often use a minimum with of 1280px. The 11" is capable of both so it's doable. It might be necessary to plug in an external monitor at times for testing but you should be able to write to the code. Anything short of a 17" LCD might require an external monitor depending on the resolution you are supporting. I don't think speed is an issue.
Hi, I know about web design, there are several years of experience in my back
the issue is more about RAM and CPU as I use photoshop for the designs I then I code them with Coda, I used to work in a 15 MacBook pro before buying the iMac.
I intend to keep the iMac for day by day usage, I'm not going to trade the iMac for an Air, the Air is going to be an extra computer.
My iMac has 8GB of RAM so RAM is not an issue in that machine , but only 2 GB not upgradable ones on the AIR...I don't know how...
