I just downloaded and burnt the slipstream version of XP pro w/ service pack 2 off of windowsbeta.microsoft.com

I'm going to try it out tonight, but before I do, is it worth it or are there any major problems with it that sould make me not want to use it on my main computer?

I can't say as I've not tried it out but I'm most likely going to wait until the official release of SP2 before slipstreaming

MS slipstreamed it for me on the site... you can download the whole deal and burn the image complete with its own serial number.

That's a nice feature, I prefer to slipstream it manually so I can include third party drivers too

How do you include third party drivers?
