They're the Jordache of PC's. All name.
My Dell is awesome. $900 and better than anything Apple could produce. 2.8 ghz, 19 inch monitor, a gig of memory and DVDR
(I'm sure this statement will draw scorn)
Not scorn, just that I'd point out that for roughly the same money you could have a faster Mac mini with better software, a more stable OS, a firewire port, better video/graphics capabilities, support for bluetooth & WiFi, and a drive capable of not only reading DVDs, but burning them as well (and also being able to burn CDs). Oh, and you wouldn't need an anti-virus application. :-)
clock speed can be compared between the g4/5 and the x86 architecture.
19 inch monitor
19 inch monitors run from 175-300$
a gig of memory and DVDR
So a mac mini with 1gb, DVDR, and a 17 inch monitor runs 1,050 a touch more than the dell but its the equal.
