Oh yeah, moved on to what? What has replaced those things and rendered them obsolete? On-board storage sure didn't, that's small and not portable, and we already had that. Bluetooth headphones didn't, those require special hardware, have to be charged (battery), have higher latency, reduced sound quality (lower fidelity), packet loss, and spyware built in, and DRM capable. Not even close to a replacement for analog h…
The storage on the device is portable when the device is portable. There are very few instances where I'd find an SD card acceptably portable but a phone not so. Phones these days come in hundreds of gigs of storage. My current phone was a decently cheap one and had 128GB of storage, easily >100GB of usable space. On Android one can easily mount the storage as a USB drive and transfer data at high speeds. And given i…
One can? I thought one actually can't, because a) the internal storage is using a file system Windows PCs and Macs don't understand and b) you can't simultaneously mount the internal storage on both your phone and your computer because that would only lead to data corruption. And unmounting the internal storage while the phone is running isn't possible either, because that's were all your apps and settings and whatnot are stored.
Hence for a very long time now you can only access your phone via MTP, which can be annoyingly fickle and less stable.
Conversely, an external SD card that only gets used as additional storage space for documents, music, pictures, etc., actually can be unmounted and at least in principle be switched into true mass storage mode (although in practice this might require root, and I don't know how well this still works on current phone models that still feature SD card slots).
