Most of 'em. Here are some highlights.

• vi/vim. The one true text editor
• thunderbird. Standard email client
• musicbee. Absolutely the BEST audio player/organizer anywhere. Sadly, not available on Linux
• potplayer. Just a simple, high quality video player
• LibreOffice. Used to be almost as good as MS. Now it is far better.
• FIrefox, sort of. I’ve lately switched to Waterfox, which is from the same code base as ff.
