[Ubuntu 11.04] Ubuntu 11.04 or any other version of Ubuntu has very high frequency of releasing new versions which makes it very unstable and there are always a lot of crappy bugs waiting to fix. so it doesn’t seem – suitable for production/personal environment, even though LTS (Long Term Support) versions can be used in production environment. [Windows 7] Windows 7 is very stable as compare to Ubuntu 11.04, so well suitable for production environment. [Points]
