It's clumsy over a LAN, nevermind the Internet. Apple's VNC is not a patch on something like Microsoft's RDP. It's a poor solution, and depends on you having a good connection at the remote end. And you'll also be using a tiny iPad screen. If you buy an iPad Pro and Magic folio and a Mac Studio then you've probably spent as much as a MacBook Pro.

Though fair warning the client (and server for that matter) are a bit janky by end-user standards.
