After talk of the 'iPod effect' attracting new Mac switchers, analysts have begun speculation on the 'Boot Camp factor'.

Apple's future technology to enable Windows to boot on an Intel-powered Mac seems set to drive market share for the company, according to Piper Jaffray. The analysts expect Mac sales to rise - perhaps by the end of the year, a report claims.

The conclusions are based on chats with 42 future PC shoppers. These talks showed that 8.3 per cent of those in the market for a new machine may turn to Mac - with Boot Camp the deciding factor.

Analyst Gene Munster predicted the software would have a "significant role" in driving Apple market share gains across the next 12 months.

Munster rates Apple stock as an 'outperform' with a $99 target price.
