Heh swomeone knows their computer history... Windows ripping off Apple is of course correct, wanna go back more than that they didnt even write DOS originally, bought it from some other guy but I cant remember the name of what it was originally
Anyways if you are using E17 dont bother with the extra programs, it has a built in interface for what it calls epplets, and expect to see lots of them shortly after E's release, or code your own. E typically does a good job(At least in e16) not slowing down your system to much though.
And Gnome isnt to bad for slowing down the system, especially in Distros like ubuntu. I know several people that have done audio work in Gnome for example, it definitly is better for it than KDE.
Though yea most that are used to linux use fluxbox, it just shouldnt be your first choice if you want fancy looking stuff
Used all of the above and still searching, waiting to see how fast e17 will run.
