How does this differ from having multiple windows open all the time. I usually have my email always open, a photo editing program open, a ftp client in another window, three online windows open, the egw disk is always open, and who knows what else. I generally have more than a full task bar full of open windows and some have multiple tabs open.
So, what am I missing? what will I gain by having two or three desktops. I have tried to clean them off by placing my often used programs on the taskbar. So, in reality my computer desktop is fairly clean. A lot cleaner than my real desk!!
