MacCentral explores Apple's Annual Report (SEC form 10-K).
Overall Mac unit sales have been relatively flat from 2001. Laptop sales and "Software, Service and Other Sources" (including the iPod) have enjoyed increases year-to-year... but PowerMac sales remain slow.
MacCentral pulls this pertinent quote from the filing:
- "[Apple] believes that many of its current and potential customers believe that the relatively slower MHz rating or clock speed of the microprocessors it utilizes in its Macintosh systems compares unfavorably to those utilized by Windows-based systems and translates to slower overall system performance. There have been instances in recent years where the inability of the Company's suppliers to provide advanced G4 and G3 microprocessors with higher clock speeds in sufficient quantity has had significant adverse effects on the Company's results of operations."
