Evolution is an e-mail program that works on the Raspberry Pi and that also incorporates calendar, contacts, tasks, and memo features. The Raspberry Pi isn’t the ideal machine for this kind of application. Usually, you’d run something like this in the background while you do other things, but with the Pi’s limited memory, it can be a bit slow even when it’s focused exclusively on these activities. E-mail is one of the most popular computer activities today, however, so if you’d like to try it on the Raspberry Pi, give Evolution a go. You can install it using
sudo apt-get install evolution
It appears among your Office applications in the Programs menu.
