Sounds about right. You would probably be able to run on less RAM or even a slower chip but it will be slow going. That is if VISTA allows you to install on that little, as with Server2000 and 2003 it might simply tel you that you dont have what it takes and switch off. I would also be sceptical on how well a Celeron processor will do and would recommend people taking this oppertunity to move on to 64bit processing.
Also, as far as Norton and anti-virus programs are concerned I found out that Microsoft did some serious re-writing of their Kernel and VISTA now incorporated, to some extent, memory randomisation. Essentially features and applications are placed at random locations in your system memory so a virus that was programmed to target a specific part of the operating system has a very small chance of finding it. Linux also does this and it sounds like it makes for a nearly virus proof operating system. Or so they say.
