I've ordered a MacBook Pro but I still had a few questions so I called Apple and asked. Here they are in case anyone is interested... Q) How does the battery life to compare to the latest PowerBooks? A) The battery lasts on average 5.5 hours. It definitely lasts substantially longer than the current PowerBooks. Q) After running a PowerBook and a MacBook under full CPU load for 20 minutes which would be hotter? A) Although the MacBook still gets hot it does run slightly cooler than a PowerBook Q) How loud are the MacBook fans? Are they louder than a PowerBooks at full speed? A) The guy didn't know. I asked if he could find out and he basically said no-one there had been given that information yet. I called the UK Apple line so if anyone in the USA wants to call and ask the last question to see if they know I'd be really interested to know the answer to that one. Thanks.
