So now we have:
New iMac with a 3 ghz processor= $1299
New Dell with a 3 ghz processor= $599
How many consumers are going to think that OS X is worth $700, because that is what they are going to see.
At least before you couldn't make direct comparisons.
Not really. If the power of OSX lets you run apps at a "perceivably" faster speed and also has no spyware and viruses, well then the direct comparison is good right? You could , for examle, buy a 1.5 ghz machine that gices you the same effective speed as a Dell 3.0 machine.
