Thanks to everyone that has responded so far....very interesting to see the range of laptops/OS's, etc that people are using... One of my main reasons for asking for this info was to see what size display most people use to do dev work on...if I'm not mistaken, while there is a range of sizes from large to small, most are tending towards larger size; 13" or larger....which I suppose makes sense given the convenience of having more screen real estate to use...
