.NET possibly no longer a concern for PA users on Vista
The .NET framework comes through Windows Update and is classified as "Important". I know because I got it today. Now I don't know how updates work on XP nowadays, but the default in Vista is to download and install all updates as soon as they are found. This means that almost all machines with an internet connection running Vista will have .NET 3.5 now. Of course, this doesn't mean .NET is no longer a dependency to worry about since XP is still what one typically encounters, but those who routinely work with Vista will now likely to be able to use .NET apps without worry.
