Seriously, mxp, you should ask them about the swap. Dell is sending you upgraded hardware as hush money. They want you to be happy so you'll stop bugging them. You've got nothing to lose by asking to keep something they already sent you.
I've been trying to get a replacement for my 9200 due to the WUXGA issue. Today, I just saw what they're going to send me as a replacement. They upgraded my RAM, my battery, and my software.
That was very nice of them. But the boneheads downgraded my WUXGA to WXGA+ and downgraded the drive from 7200 to 5400 RPM. Ugh. More time on hold -- just what I wanted.
