I was wondering if anyone else is having major performance problems with Moble Me in XP. I was adding a bunch of contacts in and over a short period of time the respoce time was getting slower and slower until it was un-usable and then hung. The hard disk was chugging away so I checked the machine performance and sure enough it was writing to the Page File resources were at close to 100%. (there is 4G of RAM on the pc) I re-booted and tried again, both in Firefox 3 and Explorer 7. Same problem after mobile me with the contacts application open for aprox. ten min.
