firm announce widely expect refresh 17in macbook pro battery firm say offer hour operation removable case
The firm announced a widely expected <m> refresh </m> of its 17in MacBook Pro , with a battery that the firm said will offer eight hours of operation , but which is not removable from the case .
Apple 's big announcement at Macworld yesterday was not a new iMac , Mini or netbook , all of which had been rumoured , but a battery .
The firm announced a widely expected <m> refresh </m> of its 17in MacBook Pro , with a battery that the firm said will offer eight hours of operation , but which is not removable from the case .
The battery , based on conventional lithium polymer technology commonly found in laptops and mobile phones , has been integrated into the case to make the device thinner while increasing battery life , according to Apple senior vice president of marketing Phil Schiller .
Apple has also introduced a separate chip that monitors the power used by each cell and adjusts the charging current accordingly , which the firm says extends the life of the battery .
The Macworld crowd did not let out its characteristic whoops of excitement when Schiller announced the battery , even when he said that its capacity for 1,000 full recharges - three times the average achieved by other notebooks - would give the average battery a five-year life .
However , one Mac customer from the show floor was sceptical of the claims .
`` Apple says five years , but for some it might only be two or three , '' he said .
`` Look at the way guys like us travel . ''
Apple will offer a p135 take-back and replacement service for the battery .
The keynote was decidedly low-key this year , being Apple 's last following a decision to pull out from the IDG-run show .
Other than the MacBook Pro , the company concentrated on enhancements to its iWork package , including a beta version of iwork.com .
The service lets users share iWork files , including those in Microsoft Office format , and to comment on each other 's work .
Glaringly absent at Macworld were refreshes of the now ageing Mac Mini and the iMac desktop lines .
