I agree that in cases where a specific hardware is necessary and you don't want to bundle the hardware with your software, the iPad is not a bad choice. There might be some annoyances when Apple drops older pieces of hardware that would still be able to run your software but you can't offer it anymore as the minimum iOS target has been raised. In the case of that Panic status board which is apparently not much more than a webview and having that tied to a particular piece of hardware is really unfortunate.
