I'm not sure if this is an upgrade or not...

I put Windows XP back on the work laptop and gave it to a new employee who will actually need to be mobile, so now I'm on a Dell Dimension 3100. It's a 3GHz Hyper-Threading Pentium 4 with EMT64, but only 512MB of RAM... And we don't have any extra DDR2 floating around the building, so it's back to the old 32-bit Windows XP for me too.
