. . .I was just wondering what is actually 'light' about the 'lighter' versions? Do they have less features than say Ubuntu?
......expect a few posts in a month or two as I am sure to get in a pickle ;)
If one calls eye candy a feature, then yes. If one looks more towards functionality and performance, then no. Desktop Environments like KDE tie up a lot of the CPU's resources (to say the least). Xubuntu uses XFCE while lubuntu uses LXDE, both of which are less resource-hungry than KDE and many other DEs. A Windows Manager or WM can be part of a DE or can stand alone. WMs are much less demanding on computer resources than DEs, generally speaking. Hence, "lighter."
A good one for performance is antiX. If more "features" are desired, the new Linux Lite 1.0.8 is impressive, especially regarding beginners and gamers, and uses XFCE.
There comes a time in the affairs of man when he must take the bull by the tail and face the situation.
