I'm far from a poweruser when it comes to operating systems - I don't particularly needmy network performance optimized, or to remote desktop into my laptop, or ... whatever. I can't think of the other differences.

The PRO/Wireless was their free integrated (I assume) 802.11g wireless card, which theoretically has some magical synergy going on with the Celeron. I'm skeptical, but it was that, randomass other wireless card, or modem/ethernet, all for the same price.
