Basically Japanese manga on a computer club in highschool that is discovering Ubuntu.
First made in 2009 so it would be the 9.04-9.10 releases of Ubuntu; I personally started using it somewhere in the 7-8.x range. This was before the polished product 10.04 was though, and none of the stupid Unity stuff from 11.04 onwards (KDE/xfce ftw), so it can't comment on those in the first chapters. However, the series is ongoing, hence the post from mint.
The art's alright (but I seriously don't care too much about the art in my manga/anime - look at Initial D, I liked it a lot but all the faces looked ugly to me =P).
The plot and characterisation doesn't have the depth and force of a regular shonen (ONE PIECE!!! =D) but you do get the regular Japanese manga stuff in there (love the stereotypes, melodrama etc.), and it's interesting to see how a manga would work with the whole topic based on a linux distro. lol.
