Update for anyone waiting for a replacement, or needing to return a x3.
I called Dell CC center today asking "what is the status of the replacement?", and expecting to hear "Its been shipped, and your tracking number is ***, just call Purolator and they'll tell you where it is located" but instead the lady replies with "The replacement unit you requested has been rejected."

grrrrr!!
(So, I do my thing)
Me: Ok. This is unacceptable. I talked to Tech1 and Tech2 from Dell Tech Support and they both acknowledged the problem that I am having and
both told me to call CC to get a replacement. I called CC and told CCgirl what I told Tech1 and Tech2. I was guarantied by CCgirl that since my unit is still within 30 days of purchase that I
will have it replaced, at no cost to me. It has been 10 days since you have known about my problem, and in that time I have bought two SD cards for the new X3. In that 10 day period I was not contacted via phone or email to be told that my replacement x3i was rejected. So, why was my replacement rejected?
Her: Um.. let me put you on hold while I find out.
*Just under 9 Minutes later*
Her: I appoloige for the rather long wait...
Me: Ok
Her: It seems that there have been some batch problems where they are manufactured in... *pause* ...Texas...
Me: What kind of problems?
Her: Im not sure, would you like to hold while I find out?
Me: If it leads me to getting my unit replaced, yes. Otherwise no.
Her: um, Okay. Sir, because it has been more then 30 days since you orginally bought the unit I can not give you an exchange now. What I can do is tell the sales department to give you a 407$ credit towards a new unit when you return the one you have along with all the included cables and documentation.
Me: Something to the effect of: "Not good enough. Yes I did pay 407$ for it, but they are now 549$ plus tax and shipping. Listen, I got this unit, it orginally broke in 2 weeks, and I was guarantied by two Tech's and a CC rep a replacement, and thats what I what. End of story. The company you represent had some problems with some units which caused my replacement to be delayed.
Her: Sir, like I said before I -
Me: - I'd like to talk to a supervisor now.
Super comes on the line, I talk to him. He understands, gives me a new exchange number and a new order number. I try to get something free out of the waste of time. Its a no go, so I dont pressure him, cuz he sounded cool. He asks if I remembered the person's name I just talked to. I gave it to him. The End.
