I have just upgraded the RAM in our Vista laptops from 1GB to 2GB which has made a worthwhile improvement. It is most noticeable when using heavyweight apps like PhotoShop Elements and Dreamweaver which need plenty of RAM.
With Vista, Thunderbird, Firefox and NOD32 (anti-virus) running about 850MB of RAM is being used. So with 1GB there's not a lot left for other apps. 2GB is much better, and for stuff like gaming, video editing or running loads of apps simultaneously then 4GB would be good.
