FYI. I returned it with Dell support assistance and am waiting for a replacement.  
How weird. I have an x15 from Best Buy that I have to return. An x15 that I ordered from Dell and was lost for a while by Fedex (that's why I ordered a Best Buy one) but reappeared last week, was just delivered. In comparing the palmrest, the Best Buy one is a little smoother and a tiny bit darker than the one that just came. Interestingly (or not) the top lid is a bit smoother on the one that just came. I am wondering if these are normal variations from the factory, or is the not as smooth palmrest perhaps a manufacturing defect? Should I not worry about it, or could it be a setup for some sort of problem later? Thanks
x15 R1, palmrest not completely smooth
