I'm personally trying to move away from installed software (which ties me to a computer that also has the software) and more toward hosted solutions where the only interface I need is a web browser. Currently evaluating one of the Google Apps things (MavenLink I think it's called) and another platform called WorkEtc, but I haven't made a decision yet.
Of course these programs might be over-kill for what you're looking for, but they also might have a few things you don't realize you need yet - like the complete CRM functionality and following through with the people you've contacted once they convert.
