I'm actually getting annoyed with ubunutu especially in a network environment with Windows servers and desktops, it is painful sometimes getting it to print to my print box, connect to a server share at speed , map shares fstab is (read only) so I cannot edit it to create permanent shares (Win 7 is much faster) and a couple other things.
Now found out I cant import .pst files into evolution, I have to install some other program called "thunderbird" and then do it from there.
Installed a network printer , try to access settings and they are completely different, suppose I need another program from that.
My ubuntu system runs the same speed as Windows 7.
What impresses me most about Ubuntu is the software you get, plenty of stuff in a nice easy to find software center.
