Toolkit 4, xp, notebooks, and inbetween

Finally a version that support Visual Studio 2010, but:

“Support for XP on notebooks is being phased out and is therefore not available for this release. Please refer to the Release Notes and Getting Started Guides for more information.”

I hate it when Nvidia decides one day that your computer is obsolete, or that you need two gpus for debugging. Moreover they still have a developer driver for desktop computers. I don’t get it, they just ignore a group of users. And if someone there thought that XP is obsolete:

or do I need also to give statistics for notebook users?!

I mean WTF, are they trying to deter users??
