OK, I probably going to upgrade (despite the fact that I wrote in on response sere that I cant justify the upgrade from my 13 PM).
And here is why (what is in my heaad after wathing mobile phone release events)
But, as i Have written in signature I using both (android and iOS). I upgraded from Samsung S21U to S23U, did i needed it? No. Did I wanted to? Yes - I wanted a bigger screen and I liked the idea of using S-pen. (I ged 512GB version and now using 150GB).
And it is simmilar with my 13PM, this phone doing everything that I need and I like it. One of reason is resale value which pay half on new 15PM and second bigger is that.
After seeing Samsung event sooner this year and Apple event now (Sorry Apple, this was most boring event that I seen from you). The last two models was exact the same with minor tweaks (s22 vs s23, new processor, new camera about which i don't care, looks almost same) and now 15PM vs 14PM, againt, better CPU, camera was is same (5x zoom - it is just cutout(?), display is same... really changes this year for me are UsbC, titan case, and action button instead switch), Oh, and yes - you can play console games on it.
So after these last few years, I personally think we have hit a ceiling with innovation and features. Yes there is always a more powerful processor, maybe a better camera or more storage or faster charging, bigger batteries,maybe new design, but these are all small updates. And I don't think that's going to change in the next few years.
I think we're at a similar level to PCs, every year there are new CPUs, new netbooks, more storage, but it doesn't excite anybody anymore. There are still a few individuals, but most people use their PCs and laptops until they break down or are slow (my PC will be 9 years old now and it still handles most of the things I need.)
So I think it's now time to get a good phone with large storage and keep it for a while.
I am not saying that I going to preorder one right now but I will upgrade and keep my phones for a longer period.
