Yeah but it's also a locked ecosystem, so no thanks. The nice thing about a device like this is that it's purpose built: it can basically do one thing, and claims it does it well.

An ipad is a walled garden of expensive hardware and software that does everything, at a high price. Those are completely different worlds, and if we're talking "it costs a lot of dollars", I already own a universal tablet monitor. I don't need something that does less and costs more.
