The MS Office entire suite is completely covered by LibreOffice. Chrome is a better browser than Firefox (IMHO) so you don't need Firefox. Thunderbird has long since been left behind - you can do everything Thunderbird does with better web clients. Outlook? Gmail, Google Calendar, etc., do all of that. Works? you must be kidding! The other programs you list probably will run on Linux under Wine but if you need a Windows computer for one or more of your programs, hang on to an old one, but you will pay the price of having a computer that does not work a lot of the time, gets viruses, and gets updated by MS right when you are in the middle of doing something important. And Garmin Homeport? What is that? Support for a dedicated Garmin chartplotter? Dedicated chartplotters are on the way out, being replaced for a lot of folks by iPads and some very capable navigation apps. In fact I heard commercial airline pilots have abandoned the tons of paper maps thye used to carry for iPads in the cockpit, does that match your experience? And iTunes, I acknowledge there is no Linux equivalent, so I have my MacBook Pro, which is not 1/10th the computer my Chromebook is at 1/6th the cost - it is slow and has spinning beach balls that drive me nuts, but I hang onto it for iTunes. Obviously you should stick with what works for you, but this thread started off with your complaints about Windows! I will only say MY computing experience has been enhance by an order of magnitude since I switched to a Chromebook with Linux
