At Dave126, RE: 32GiB.
So I'm supposed to fit *TiB* of music into a 32GiB phone & expect that to suffice? A 32GiB SD card isn't enough to only take a single track from each artist/band in my collection, much less any reasonable portion of the collection itself. So while *you* may consider a 32GiB fixed-capacity device to be sufficient for your needs, please don't make the mistake of assuming it's acceptable for "everyone". There are far too many folks for whom such a meager capacity wouldn't even scratch the surface of their music library...
And then there's other media files to add to the mix. All those movies take up a *lot* of space. How many BR movies will fit in a 32GiB space? How many 4K ones? I hope you can fit a decent selection of titles into that space because if you haven't got a signal then what's in that space is all you have to choose from to watch.
Audio books tend to take up several hundred Meg per title, and if you've got a considerable library to choose from, 32GiB isn't really enough to store a decent selection - do you want to include the entire Game of Thrones series? That'll take the bulk of the space all by itself.
You're a bit better off if you have ebooks, you can store a massive amount of those in a 32GiB space, but if they're stored as PDF then you can kiss that space very quickly goodbye.
Photographs will *devour* that space in a hurry. The bigger/higher res the pictures the faster the space disappears.
If you keep separate spaces for your apps, like one SD card for Personal & another for Work so never the two shall meet/infect, then the number of apps stored in such spaces will grow to fill said space. Everything invariably does.
Once you combine all this stuff into a single space, the capacity needs of that space quickly make themselves felt. 32GiB may sound like a lot to start with, but you will watch in dismay as it rapidly goes away the more of your files you try & keep there. Even a device with 256GiB of capacity won't last forever with all the stuff we tend to accumulate (cue the George Carlin skit about "your stuff").
BUT, if that phone has an SD card slot then you can ALWAYS give it more room simply by swapping in a new card. Old card full of music? New card = more stuff!
As others pointed out, the cost of the 256GiB phone is *much* higher than an SD card of the same capacity. So if the phone has a SD slot then it can get away with less internal storeage, you won't spend nearly as much for the space difference worth of SD cards. (As in the price difference between a 32GiB phone & a 256GiB phone could be better spent on LOTS more capacity of SD cards instead.)
See? I hope so. I need caffeine & a refill of my sanity - I'm running critically low on both.
