I've finally switched. My OS history is something like CP/M -> DOS -> Windows 3.0 -> Windows 3.1 -> Windows 95 -> Windows 2000 -> Windows XP -> Ubuntu Linux -> Mac OS X. The Intel Mac means I can run Mac OS X as my main OS (and I can drop into Linux and Windows when I need to). My new MBP 17" high-resolution, 160Gb 7200 RPM is due on Monday, before I open the box what advice do the experienced people have for me? I've heard about battery calibration. Anything else I should do with my new machine? Cheers, John.
