That sounds pretty contrived to me, even tautological. Technically these tablet computers are as general purpose as it gets. That's why it takes extra effort on the part of vendors to limit what you can "naturally" do with them. But we're talking about what they are sold as. So here's an example:
"[...] there's no limit to what iPad can do for your business."
That's what platform means. A basis for doing anything without a limit, not just some pre-specified set of tasks. They are expressly different than feature phones or kitchen appliances or automobiles.
