Tomorrow (25th of August) according to Microsoft announcements, will be the day for the Automatic Update release of Windows XP Service Pack 2.
I hope so, but I think that the Automatic Update requests will be a great amount, so there could be problems with the Windows Update service.
However, after the XP SP2 installation, I think we've to bookmark the link to the Microsoft Knowledge Base Article - 875355: How to use the Automatic Recovery feature to recover your computer if the Windows XP Service Pack 2 Setup program is not completed successfully.
This article discusses how to use the Automatic Recovery feature to recover your computer to its previous configuration if the installation of Microsoft Windows XP Service Pack 2 (SP2) is not completed successfully. Use the procedure that is discussed in this article to recover your computer to a bootable state and to remove Windows XP SP2 if Windows does not start correctly after you try to upgrade your computer from Windows XP to Windows XP SP2. This article also discusses how to collect information about the Windows XP SP2 installation and about your computer to help troubleshoot and diagnose the issue.
Bookmark it... could be useful! 
I don't know if the rumours are true, but is coming on the air the voice that Google could appear on the Instant Messaging world with a new proper Instant Messaging service based on the open Jabber protocol.
I'm a real fan of the Jabber protocol (I'm a Jabber user and it's not only a simple IM Protocol...) and if a giant like Google is planning to adopt it for a new IM service, this could be the start point for a real protocol diffusion.
Obviously, there are lots of good IM Client out (like MSN, Yahoo Messenger, ICQ etc.) so it will not be simple to attract people on a new IM product, but the open nature of Jabber could be the key for a success (you could easily build new services or a personal IM Client, you could easy interact with the IM service and integrate it with your applications for example).
We've only to wait the Google movements... personally I hope that these projects could be realized soon, I'm really curious to see the new GIM or Joogle (maybe??? ) in action...
