Just bought 2 unit of Dell E520 + Vista Business Edt to test.
Annoying popup when accessing program inside control panel. Play chess also make the whole system freeze out.
Haven't test out other problem yet..


Will downgrade back to windows XP Sp2 for sure coz Vista business/ultimate edt comes with downgrade rights. And it still able to upgrade back to Vista for future.
If the Vista quite stable for couple month, will be migrate back to it loo.
