My new MacBook Pro arrived Friday, and the first thing I did (after basking in the beauty that is a new Mac) was to start loading my “must have” applications on it it. Of these, the Quicksilver fast app launcher is probably the single most important tool I have -- using it has become as instinctive as breathing, and it’s disconcerting for me to work on a Mac that doesn’t have it installed.

A close second, at least in terms of productivity, is iGTD, a tool for implementing “getting things done” style lists on the Mac. I’m not a convert to the GTD cause (I never read the book) but I find some of the concepts useful and this is the first program that proved itself capable of replacing the paper “to do” lists I’ve been using for years.
