Sometimes Best Buy has exclusive models that have specific software put on there by the manufacturer. You can usually verify if you are getting one of those models by googling the full model number to see if there are other sellers than Best Buy out there.
They probably have slightly different hardware to keep a price edge. But anyway, to anyone on HN I'd think bundled software is pretty much a non-issue; I've always installed Windows fresh and I feel like doing that isn't a big deal if you are technical.
Well, I am an MSDN subscriber. But if you aren't, can't you get a "recovery disc" from Microsoft somewhere and then use the serial on the label? I can recall doing something like this in the past.
