Sounds like you are having a great time in Tunica!
I have the Home version of XP. I also will have that on a new Dell laptop (Inspiron 8100 pictured below) that I just ordered. I passed on the Pro version as I could not see paying the extra money for a few features I would not use anyway. Upgrading was VERY time consuming, BUT problem free! About an hour to upgrade then all the extra time to tweak everything & check that programs worked correctly. You should not have a problem.........How much memory do you have on each computer you are upgrading? I have 256 on the Dell I just upgraded & the same on the new laptop. Let me know if you have any questions once you get ready to upgrade. Andy - Las Vegas
