In addition to unprecedented iPod sales, Apple also experienced better-than-expected sales of iBooks in the second fiscal quarter – in line with the predictions of Morgan Stanley analysts. However, poor Power Mac sales have given some analysts cause for concern.

Trusco Capital Management analyst Patrick Kirksey told Bloomberg: "Investors were disappointed by Power Mac sales because they fear it shows the new G5 model isn't catching on quickly," on a positive note, he added: "The Power Mac number wasn't stellar, but it beat a lot of street estimates I saw. I was tickled pink with the quarter.''

Apple had indicated that it hoped to achieve 200,000 Power Mac unit sales in the quarter, but admitted in a conference call with analysts that it now expects some quarters to see more sales, and others not to meet the 200,000 target, "depending on the product life cycle and seasonality".

According to one analyst present on the conference call, Apple's year-over-year increase in CPU sales (5 per cent) was only a one-third of the industry growth. Senior vice president of finance and soon to be CFO, Peter Oppenheimer said: "That was in some part due to reduced channel inventory, now at 4-5 weeks." This reduced inventory is thoughts to have significantly affected Power Mac numbers.

Apple also admitted that slow Power Mac unit sales were partly a result of Xserve G5 shipping delays. The XServe G5 began shipping in late March after delays caused by IBM's PowerPC, according to Apple. Apple confirmed that it expects to have fulfilled all outstanding Xserve orders by the June quarter.

iBook sales up

Apple shipped 201,000 iBooks in the quarter – resulting in $223,000 revenue. These sales represent a 51 per cent increase on the same quarter last year (133,000), but no change on the first quarter 2004, which also saw sales reach 201,000.

All other Mac variants saw a decrease in unit sales. iMac and eMac sales combined to reach 217,000 units – a 15 per cent decrease on this time last year (256,000) and a 4 per cent decrease on the first quarter (227,000).

PowerBook sales were 157,000 – 19 per cent fewer than this time last year (166,000), and 5 per cent fewer than last quarter (195,000).

Power Macs and servers combined to make 174,000 unit sales – up 12 per cent on quarter two 2003 (156,000), but down 16 per cent on the last quarter (206,000).

However, sales of all variants of Mac computers totalled $1,160 for the quarter, representing 60 per cent of overall revenues – which were $1,909.
