I’ve taken the plunge and moved from Windows on my Surface Pro 3 to Ubuntu, and while the migration wasn’t so bad it can be challenging to find software that does what you need on Linux when you are used to Windows/Mac OS X.
Here’s some replacement programs with instructions to install.
Note I have also included programs that do exists on Linux (some to my surprise)
Replacement: Keepass! this was an easy one.
Install via apt-get:
sudo apt-get install keepass2
Replacement: Steam! This is also available for Linux
Replacement: Spotify! This also exists for linux
