Last week, I took the liberty to install Windows Vista and even went so far as installing Office 2007, IE 7 and the like (of course all beta versions). To my utter dismay, it was a frustrating experience.
Much before, I could begin to appreciate the virtues of Vista and its family of products; I was constantly disappointed to see the browser freeze on me repeatedly. So much so that I decided to uninstall the above, restore my machine to its original factory settings and go from there.
The moral of the story is to let Microsoft fix all its bugs and wait for the RTM. Until then, make hay while the sun shines!!!
