LaTeX is a cool type-setting programme that I use. It is free to use/download, and offers templates for journals in the sciences (e.g., Elsevier journals).

Once you get used to the programming language and its idiosyncrasies, I guarantee your Word days will be over, and you'll never look back! There are loads of on-line forums etc. to guide you through the initial complexities, so give it a go.
r is quite simply the best stats/graphics programme available. If you look at my stats page you will see some introductory code to get you started. It is completely free to use/download.
Great email client by Mozilla. Nice free alternative to Outlook. Will sync with all the usual mail providers.
I plagiarized this from their website: one of my favourite online resources; would highly recommend to everyone wishing to enrich their knowledge!
