For The Most Part, OnLine (Web Based) Services Have a History of Secure &
Reliable!
....& I Would Venture That, ISPs' Are For The Most Part, Reliable As Well,
Excepting The Occasional Outage!
Look! There's a "Track Record" For OnLine Services; Hotmail, Messenger, etc.
....& It's a GOOD Track Record!
Why Wouldn't It Be "Good" For a Web Based OS: The Windows Live DeskTop -
Powered By Windows Vista Hosted On Microsoft Servers?
