I don't what someone without access to the systray does in that case.
Personally, I haven't used the 'Windows" taskbar/systray for years, but I always have access to some form of the systray. At first, I used NextStart, then I went to HoverDesk. Now I use ObjectDockPlus, with a Running Tasks dock, and a Systray dock. So, even though I have "no systray" in the tradition Windows sense, I do indeed have a systray, and one that looks so much better than the original.
