Ditching the SD card slot and maxxing storage out at 512 is a real backwards step IMHO and means the only current reason I could be persuaded back from iPhone to Samsung is now gone.
If I can't take my lossless music library on the go, then I might as well stick with the Apple ecosystem for my needs.
I am someone who really needs an expansion slot as I take a lot of photos and videos. If I bought the S21 Ultra I would need to spend $2450 for the 512GB version. Ouch.
The S21 Ultra a disappointment for how I use my phone.
