Truthfully? I don't find it difficult at all and I'm not tech savvy, lots of people saying that they can't live without this or that or can't mix and match between devices, how hard is it? I can get all my e mails, calendar alerts, messages on my Galaxy S23 Ultra, I use WhatsApp, I have never worried on messenger if the bubble is blue or green. As for a watch, I have never had a Samsung watch but have had a Apple Ultra and series 8, I also had a Fenix 7 which was by far and away the best smart watch I have ever had, the Garmin app is so much better than Apple health.
I'm no Apple basher, just look at my sig.
I don't use my watch to make phone calls (I did have that facility on both my Apple Watches but never used it), so I will be buying a Garmin Epix 2 which is basically the same watch as the Fenix 7 but with a better screen.
The Samsung Galaxy S23 Ultra is the best, most polished phone I have ever had, the apps work beautifully and strangely there is no lag, because that is the excuse that is made by people that have never had an up to date Samsung flagship phone but quote opinions of 5 years ago. I sold my iPhone 14 pro the other day because I regard the S23 Ultra as a better phone.
I will keep my 3 different iPads and MacBook Air because I think they are fabulous and can't be beaten, wish WhatsApp did it with iPad but it's not a game changer.
As I said before, I am 65 years old, just learning how to use this technology, but in relative terms, a novice at it, but, Ill tell you what, if all you can use are Apples products and can't mix and match devices from different companies, you're either making up excuses to stay Apple or, you are worse at Tech than me and that's saying something.
My Phone will be a different make from my watch which will be a different make from my tablets and Laptop, which are from a different maker of my ear pods which is different from my portable blue tooth speaker (Ultimate ears) which is a different make to my Naim music system which can be controlled through my phone or iPads which is different to the Sonos speakers I have in the bedroom which are a different maker from my lighting system. It all just works together, from my phone, tablets, computer or, in some cases, just asking Alexa to make it happen.
