It's a statement of the facts, and suggestions of other ways to alleviate space concerns. I'd say it's a good answer, even if it isn't the one you want to hear.
Those "other ways" are either not possible with a tablet or just plain old stupid. There's NO WAY for consumer to change out the eMMC. The Dell Venue 8 Pro for example, there's no way to increase storage space from 32GB to 64GB. As for deleting unnecessary
files, what files would that be? The only files I have on there are either apps, windows file, and media files. There are no junk file accumulating. I've even had my OneDrive files sync to SD card and it doesn't help. Keep in mind that Windows allow multiple
accounts and each account have their own separate set of apps.
So, stating the obvious is not helpful. Same goes for the suggestion that we increase memory (by the way, it's storage, not memory) and deleting unnecessary files.
