PCLinuxOS “KDE MiniMe” Edition
This Linux distribution may be mini at an under-500MB size, but it packs in a lot of OS for something so small. In fact, PCLinuxOS 2011.07 could easily be mistaken for a full-sized distribution given there’s nothing in it that feels slimmed down/compromised for size.
Personally, I think this is definitely one of the better smaller distributions out there. Smaller is good when it comes to an OS, but not when it takes away too many features and functions. PCLinuxOS doesn’t feel watered-down in the slightest and is solid all-around. See video below for details.
