Err... okay... I looked on Dell's site like a week ago, found the upgrade, saw it was $29, decided to wait on buying it. Now, I can't find it anywhere on their site, and the knowledge base article says it hasn't been released yet. I've spent a lot of time on Dell's site the last two days looking around, and I haven't managed to find it anywhere. Am I doing something stupid?

Umm, assuming I can ever find it, is it worth buying?

Dell pulled it from the website a few days ago. You have to order via telephone.
