Editors' Review

Prism lets you take Web-based applications and convert them into desktop applications. While it performed well during our tests, were trying to figure out why anyone would find it necessary.

The programs interface appears as a pop-up window and a blank browser window. There's no Help menu, so we had to play around with it to figure out just what, exactly, it does. Basically, you enter a URL and a name and a shortcut appears in a location of your choice. We chose to place a shortcut on our desktop, and sure enough, when we clicked on it, the corresponding Web site appeared in the Prism browser window. The browser itself is plain and lacks any navigational buttons, which was really frustrating since the app is still Web-based and you can't go back to the last page.

If you could view the pages offline, we could understand the point of this program. From what we understand, the program is still under development. We think its best that you wait until the makers of Prism finish what they've started before you give it a try.
