I have a few questions about the 15 inch powerbooks (pref. with the 1.67 processor) what is your battery life running normal programs/surfing the web? If anyone uses Final Cut Pro does it kill the battery time or not much difference? Is it OK to use it while sitting on your lap or will the extra heat kill the powerbook (dont wanna risk anything, it happened with my toshiba notebook) If anyone has any comments about it for every day use and video editing they would be greatly appriciated. Thanks in advance.
