Its a bit difficult to grasp the concepts and differences between virtual
desktops versus activies. I found the excellent blog of Chani, who
develops on KDE activities as well, very help ful in understand
activities. For example:
{December 26, 2010} Activity-oriented vs Application-oriented workspaces
http://chani.wordpress.com/
were she describes the differences between GNOME 3 and KDE in that regard
or her screen casts like
{December 18, 2010} Activities 4.6 screencast
http://chani.wordpress.com/2010/12/18/activities-4-6-screencast/
or
{January 9, 2011} Activities in Action
http://chani.wordpress.com/category/activities/
I also darkly remember a blog entry of her or someone else that explains
the difference between activities and virtual desktops in a really clear
way. Lets see whether I find that one. Ok, it might have been that one:

of Jason "moofang" Lim Yuen Hoe.
Yes, thats it.
I found it through
