Bridges the gap but not entirely Rated 4 out of 5 stars
Whilst Prism does bring the web a bit closer to the desktop, it doesn't integrate tightly enough with either.
Web: Have a Stylish style that alters an app to your liking? A password manager that signs you in automatically? Bookmarklets to quickly perform various tasks? You will lose all of these things with a Prism app.
Desktop: Much better integration but doesn't currently work very will with Win7. That is fine for now but Prism will become increasingly irrelevant unless support for jump lists + Superbar is included.
