Cons
Con Installer doesn't recognise partition table SOMETIMES
On a couple of occasions the installer has told me one of my disks is missing a partition table but it definitely has one and other distros haven't presented this warning.
Con Default theming not to everyone's tastes
The default icon theme in particular is IMHO pretty ugly. Easily changed but if you like to just plug & play without changing themes it may not suit you.
