Windows XP SP2 possible little known fact

I know there is a bunch of news out there about the new RC1 of XP SP2 but I found something on a forum that you might find interesting.

 

If you install the new SP on a Tablet PC it will update it to “Lonestar”, which is what MS is calling the soon-to-be-released update for Tablet PCs.  I had my hands on a Tablet a few days ago but had to send it back to papa.  If someone out there who still has one could install the update to it and confirm??  TIA!
