REMEMBER every Vista release out their is beta for developers.
SO do NOT use it to judge Vista's reliabilty, performance or stability.
AND read the samll print ... MS dont' say you can uninstall it cleanly .... WATCH what you install , you may have trouble and find it won't uninstall cleanly.
This happens every time MS do pre-releases and it gets into the public forum.
