I pondered this for ages, as I wanted to get rid of my "borrowed" XP Pro. I opted for purchasing Home version, and having now run both versions, I believe Home is well sufficient for my need.
And of course, if you have an old copy of '95/'98, you can re format HD and do a clean install with the UPGRADE versionof Home, as it only asks for verification of previous Windows O/S - it does NOT have to be pre installed (but this does not appear to work for system restore packs - you have to have version installed - but kept in background).
