Agreed. Being able to pin specific app pages or features [edit]on WP7[/edit] is another example of apps moving towards a linkable page paradigm. Both have merit

Agreed. Being able to pin specific app pages or features [edit]on WP7[/edit] is another example of apps moving towards a linkable page paradigm. Both have merits, and both have scenarios in which they're more suited to their particular environment. Case in point being anything that requires encryption. I've seen .js implementations, but the web adds so many other threats not faced by apps that could completely undermine its use (depends entirely on the ability of the developer).
