In education netbook user here too. I use Kubuntu (not netbook remix). Before that I used plain vanilla Ubuntu (switched to KDE after problems with Unity).
I find it works well for me, but I have a fairly powerful netbook (if there is such a thing), as opposed to the really light ones that first came out.
My old one (800mhz celeron, 512MB RAM, 2GB SSD, 7" screen) struggled with anything heavier than Lubuntu, and only has that on it because /var is on a separate 8GB SDHC card. My daughter uses it now to play angry birds through wine.
My current one is better (1.6 Atom, 2GB RAM, 160GB HD, 8.9" screen, 90% scale keyboard), so manages full *Ubuntu better. I think if I still had a smaller keyboard like my old one, it'd have driven me batty by now.
