A bit delayed and short, but this month I have the challenge to only use Linux (Ubuntu). I have no MS Windows OS installed anymore, no dual boot or such a thing. I still have a Mac in the house but this machine is not used by me.
Finally only Ubuntu for me! I will be using Ubuntu 11.04 with Unity on my Notebook and my Desktop machine.
A short retroperspective to last months challenge: I think wrapping up (at SAP) worked really well. As far as I know I left in good conditions and without any escalation.
