Are there anymore issues with receiving the XPS 8900?

Hello,

I've read a few posts about issues with delays of shipments for the 8900s. I purchased a special edition March 7th and it says the expected delivery date is the 16th. It is imperative that I receive the computer no later than this as I am using it for my lab. I go to a university and all of my classes revolve around it.

Have the shipments for this desktop been accurate lately?
