I use 2 computers on a KVM. One for work/projects and the other one for "everything else." The work computer has all alerts and feeds off (including email).

I use 2 computers on a KVM. One for work/projects and the other one for "everything else." The work computer has all alerts and feeds off (including email). I find it gives me a psychological separation. If I really need to work or hit a deadline, the non-work computer goes off.
