The recent cancellation of the PowerBook G4/15″ model in the wake of MacBook Pro shipments might give an indication of how PowerPC-based Macs have been selling during the Intel switch, as Macworld UK notes.
The article notes analyst Keith Bachman, who employs NPD data which suggests Apple’s January Mac sales grew - but not by much, year-over-year, in 2006. Instead of the 20-something per cent unit growth figures to which we’ve become accustomed each quarter, the NPD data indicates Apple’s Mac unit sales increased by only 6 per cent in January. Revenue is estimated to have swelled by a mere 1 per cent over the same period.
