I am applying for a position in a non-profit. I think I would be able to achieve more using a mac. However, the non-profit uses Windows with Office applications. Word is fine. However, I will be using access for creating databases of volunteers and employee's. I will also be using windows for invoicing, schedules, contacts, budgeting. How could I do all this better on my mac? And, how can I start using my own powerbook at work?
