Geeks tend to forget that there is more to a computer than raw numbers.
Design, noise, materials, software (try getting that inspiron with apps like garageband, imove, pages and numbers for less than $1099), support (walk into the apple store and someone's there to help) and general ecosystem (time machine, app store, UNIX foundation (no real viruses)).
You're right of course. Honestly, I wouldn't buy any of them myself (the iMac included). But getting a better user experience does count for something. I'm just lamenting that it looks like the return of the Apple tax, which was thankfully going away with things like the MBA and the rMBP which really were better than similarly priced offerings.
