Having gotten sick of Windows 7 Starter Edition for being so ridiculously slow on my Netbook, not long after I bought it I installed Lubuntu so that I could actually get things done without having to wait an age for stuff to load (and that was after an upgrade to 2GB of RAM).
So, since then I have kept Windows 7 on my netbook for the sake of being able to do stuff I only knew how to in Windows, and because I was not entirely used to/comfortable with linux yet. Now, however, I have decided to make Lubuntu my permanent OS on this machine, my only gripe being that the default Desktop Environment isn't exactly the most pleasant to look at...
I understand that this is partly because of the fact that it is so lightweight, and my Netbook might struggle with some of the effects in full desktop OSes... However, there must be some still relatively lightweight alternatives which look nicer.
I'm jealous of how beautiful an interface Ubuntu's Unity is, but I wouldn't dare try and run it on this little thing.
