Mac Book Pro Must-Haves

Haven’t decided whether it’s December or January, but there is a new Mac Book Pro in my immediate future.  Beyond the obvious Adobe packages I plan to install, not sure what other things I should consider, so I’m taking time to ask those exsiting MBP owners that work in this industry (programmers, that is) – what are the software packages you consider ‘must haves’ for this machine?

Thanks for your time and comments.
