I am in the process of buying a new PC which comes pre-loaded with Vista. I quite like XP and would rather have this OS. I managed to get a dodgy copy of office which has all sorts inc visio which I need. From reading reviews of Vista, they mention that Vista is all over unofficial software like a tramp on hot scoff. Is this right ? I believe you can buy original copies of XP or Office through DCSA at a reduced rate. Is this correct ? Any help or advice on the best way forward would be appreciated as if I have to buy XP and Office, this would have to come off the PC budget which isn't ideal.
