It should be a good thing. As is, there are lots of one-off use cases for apps where people simply choose to do without. As an example, if I'm buying a product online (and not from Amazon), there's probably an app for the marketplace that's more mobile-friendly than the website. But right now, I still choose the website because it's not worth actually downloading something. With Instant, I can pick the better one without the hassle and commitment of adding something to my phone.
