Ubuntu MacBook: Overall
Switching my MacBook from OSX to Ubuntu on the whole has been a good experience. Regrettably I will have to put OSX back onto my laptop. This is mainly because I need to be able to use Skype with video in my work. I do plan to setup a dual boot on my machine as soon as I get time.
I am going to use Boot Camp to get the drive partitioned and then put rEFIt on to manage startup.
I am most likely going to go with Kubuntu over Ubuntu. I have always primarily been a KDE fan when it comes to a graphical environment in Linux (plus I am looking forward to trying KDE 4). However over the last few years it seems like Gnome has been getting a larger emphasis from the community. So I have been trying to make myself use it more often, but there are just little things that will annoy me on Gnome or I will run into something that I like better on KDE.
The applications packages built for KDE have a lot of nice stuff in them that I like better than the GTK equivalents. Like Amarok over Banshee; or Kate over Gedit. I also really like Kmail and the related Koffice applications over Evolution. And all of those applications just run a lot smoother in a KDE environment.
Another one of the things that gets to me is that it seems the KIO interface works a lot soother than the IO interface for Gnome. I was always fighting with loss of connectivity when it came to dealing with Samba shares or SSH mounts.
Gnome is very much a capable and user friendly windowed environment, but I just prefer KDE overall a little more.
Anyway, if I don’t end up using a form of Ubuntu, I will probably go back to Fedora (my old favorite), because I have been hearing good things about the new version.
