Thanks for the replies. Why do I want Office 2003? Put simply, it's what I use at home and at work, and I'd rather have the same version everywhere, so Office isn't constantly trying (and usually failing) to convert all my work between different versions! Also, something I forgot to mention - I think in the light of how much my laptop will struggle just running XP and Office, I won't use it for anything else at all (will have a separate Win98 partition for emails etc...). As this means I won't be connecting to the internet in XP (hence ruling out most of the benefits of SP2 I guess), will SP2 be a help or hindrance to speed/hard disk space. I'm not averse to the Win 2000 option though. Is it a much less resource-hungry operating system?
