ME runs just like Win98SE. One new feature which I have already used is the 'System Restore' function. Somehow after a routine windoze freeze it couldn't find some drivers on the subsequent reboot. 'System Restore' enables you to set a date when things were working and loads accordingly.
The other new (sic) features are already available FOC from the MS web site. Conclusion - well worth 100 baht, but I wouldn't pay any more.
