I have my MacBook Pro connected to a CalDigit TS4 Thunderbolt docking station. It provides power, 2.5GbE, multiple monitor connections, USB-A, USB-C, etc... I then connect the dock to a dual DisplayPort KVM. This lets me easily switch between my Windows Gaming PC and the MacBook Pro in my office. I really love being able to simply disconnect one USB-C cable and grab the MacBook Pro when on the go.
Password manager as well.
I'm trusting Apple. LOL
Another tip you may not be aware of as an Apple iPhone newbie @velvetfoot:
Occasionally if you have any weird lockup on the phone or an app is not working correctly after fully closing it and re opening - the way to do a sort of soft reset/reboot is:
In quick succession press volume up then volume down then press and hold the right side button. Ignore the power off prompt and keep holding the side button until the Apple icon appears.
The above sorts out some strange quirks from time to time. I've just had 'pinch to zoom' stop working within my Hikvision Hik-Connect CCTV app and assumed yesterday's iOS 18.4 update had broken the app. Rebooting the app did nothing to help but rebooting the phone as above fixed it. You shouldn't need to use it often but it's good to know how..
Would I get the same result if I did a power cycle on the phone?
No - if you swipe to power off and then turn it back on again it's not quite the same.
I think I have had to do this once in over 15 years of Apple iPhone ownership, and about 5 phones. Last time was maybe 12 years ago.
Apple Passwords have gotten better over time. Any password manager is better than writing them down.
A couple other things everyone should do is set up recovery and legacy contacts
Well, not maybe any password manager. I can envision somebody making one that steals your passwords.
I really like the Magic Mouse with the MacBook.
You can use your iPhone as a mouse for your MacBook 
I really like Navigation. Will probably ditch the Garmin.
I wonder though, how well does the Apple Nav work when there is no cell signal?
Thanks.
edit: Yes, I see that you can download a map area for off line use. The are limits though. I think I'll take the Garmin along anyway, just in case I get really lost out in the sticks on some impromptu trip.
The GPS itself will work anywhere, but you need a cell or WiFi connection to load a map and directions for route-planning.
In other words, the phone might show you as a blue dot in an empty/blank map grid.
You can work around that, at least in part, by configuring Apple Maps to download an area for offline use, if you’re in that area frequently or you’re planning ahead for travel.
I’m not sure if that allows for turn-by-turn direction planning while offline, but it would at least allow you to see your position on the map when the GPS signal can connect, but nothing else can.
Probably a safe bet if you frequently drive through areas with poor/no cell coverage.
That's what I was thinking. You only need it when you need it.
It probably downloads for its own use on the fly for a certain perimeter, updating as you move. So, cell outages for a certain number of miles can be overcome.
Now, to find a car mount for the iPhone. There's like, a billion options.
If you're going to truly and fully become an Apple user, the only real choice is to buy a new car that includes Apple CarPlay functionality! (just kidding!)
It really does make a huge difference, though. I have wireless Apple CarPlay in my car, which allows my phone to stay in my pocket. The navigation using Google Maps or Apple Maps is very good, and I love having real-time traffic data available. I used to have a Garmin Nav system many years ago. I feel a smartphone provides a much better user experience these days (assuming you have decent cellphone coverage.)
Even if your cell phone coverage is spotty, if you start navigating to a destination, I believe the phone caches the maps for that particular route. So, if your coverage is spotty along the way, you can still complete the trip that you started. However, if you're in a remote area just exploring (like Yellowstone National Park and surrounding areas), I found it helpful to download the maps of the area ahead of time. This allows you to search the maps and create new navigation routes without a cell phone connection.
That's where the car's screen shows the map, right?
My 2022 MINI does do that, far as I can tell.
I can keep the phone in my pocket and use SIRI, but it would be nice to see a map.
Some models of 2022 Mini cars apparently do have Apple CarPlay built-in, based on the trim levels. If yours has Apple Carplay, it may require the iPhone be plugged into the car's USB connection.
Apple CarPlay / Android Auto really improves the phone-based navigation experience dramatically. Check it out. Hopefully, your Mini supports it already. If so, you won't need to handle your phone at all while driving. You can use Apple CarPlay for Navigation, Music, Messages, Audiobooks, etc... while driving.
I checked it out. Apparently in 2023 everybody got it. Oh well.
My much older Ford has that. Works for me on long drives because the phone stays charged. And I can play podcasts, music etc.
My 2017 Volvo does CarPlay, but not wirelessly.
Does the 2022 Mini have a screen with apps?
CarPlay might show up there, if supported.
