To my bretheren in outside sales, I absolutely urge you to take a look at HubSpot's CRM (it's free by the way!).
We all move from job to job, no matter our success over our career (we get bored, not challenged, unachievable quotas - yes, read that sales leaders, etc.) and one thing we always seem to bring with us is the elusive PST file. I can't tell you how many friends have asked me over the past year, "How do I get a PST on a MAC and I'm using Google as our email service provider?".
