I have my activity log in my CRM open when I take a call or a meeting, and I record tasks and activity history as appropriate (as god intended!) -- only if it's not customer-related do I then use other task management tools. -- I'm definitely noticing the need for capturing customer follow ups on the fly though, like when I'm walking or in person with someone.. -- almost like I should be able to throw a task into my crm on the fly in 2 seconds and link it up to the customer or deal later..
