Pay more for Linux?

Curiously, if you spec up the Ubuntu equipped Inspiron 6400 to the same spec as that offered for XP or Vista, the price for the Ubuntu laptop is higher (405.37 vs 398.99).

The basic spec Ubuntu laptop is cheaper (at 329), but adding a comparable processor (dual core), memory (from 512 to 1024), and optical drive (DVD/CDRW to DVD+/-RW) makes the Linux lappy more expensive.

With pricing like this, smart Linux users will buy the Windows lappy, and install Linux themselves, whilst Dell will drop the Linux option due to lack of demand...
