I have slowly but surely been moving my life from the PC to the Mac. Here is a list of useful things:
Moom - a very cool tool for moving and zooming windows
Mint - from Quicken - a wonderful replacement for Microsoft Money. It is cloud-based, but makes budgeting and tracking as a family very easy.
Alfred - I use it to launch programs, search for files, search evernote, create reminders - all from one central place. It seems like every action I initiate these days goes through Alfred with its extensions.
Omnigraffle - it is not cheap, but a fantastic drawing tool. Effectively Visio on steroids for the Mac. Can even edit visio drawings and export back out to Visio.
Thought I would capture these here for future reference.
