Mac sales climbed 8 per cent year-on-year in January, according to the latest NPD data.

According to Pacific Crest analyst, Andy Hargreaves, the latest NPD data on Mac sales growth sees such growth up 108 per cent year-on-year in January in dollar value and up 101 per cent in unit sales. This equates to a 8 per cent rise in actual units shipped, year-on-year.

Mac notebook sales are significantly up – 194 per cent in unit sales growth (221 per cent up in dollar value), year-on-year, again in terms of growth rate, not unit sales.

The analyst believes Mac sales will "significantly exceed" his current estimates of 1.495 million units, a report explains.

Echoing the news the latest Net Applications OS marketshare data covering web use in January confirms Mac usage is climbing.

The latest Net Applications for February figures show Mac share at 6.38 per cent of web use. Split down, that's 4.29 per cent for PowerPC Macs and a further 2.09 per cent for Intel Macs.

Mac market share rose 0.26 per cent between January and February this year, the figures reveal. Since August 2006, Mac market share has risen by 2.05 percentage points, up from 4.33 per cent of the total market by OS. Windows Vista presently accounts for 0.93 per cent of the market.
