Select Dell Notebooks Now Cheaper With Ubuntu + Retail Vista Than Vista Pre-Installed

In cases where computers are available pre-installed with either Linux or Windows, it is almost always the case that either (a) the Linux one is slightly less expensive or (b) the Windows one is actually less expensive, so you might as well just buy the Windows version and install Linux. Apparently, this is not always the case. While comparing the prices for some Dell computers, I discovered that on some Dell notebooks, it is cheaper to buy the Ubuntu version and a retail copy of Vista than to buy Vista pre-installed.
