Re:Yes, You pay more for it. (Score 1)

The visible differences between the open source E520 on the left side of the "open source" page and the E520 on right hand side of the Windoze bargain page are:

      1. The "open source" has a 250 GB hard drive, the Windoze a 160.
      2. The Windoze version says it comes with a 16x DVD, no such thing is specified for the "open source" version, which may make the FreeDOS install difficult.
Those differences could hardly come up to $230, so you are paying the Windoze tax and then some for the illusion of avoiding it. Same box, same stuff in it, the one with Windoze costs less.

And...

The E520n as listed there has a monitor included, the E520 does not ($240 difference)
The E520n has a CDRW/DVD combo drive, the E520 is DVD-only. ($30 difference)
The E520n has a 256 MB video card, the E520 is onboard video. ($40 difference)

That should cover your $230 difference, plus $80 for your trouble.
