AG films never look good. I keep one on my iPod Touch only because it improves the feel of the touchscreen. I recently replaced the AG film on my Droid Incredible with a clear film, and the difference in sharpness is amazing. The glossy plastic film has a bit better feel than straight glass (not nearly as good as matte), and it still protects the screen from scratches.
I would strongly recommend against a matte film on a laptop. I guess you could always try a cheap ebay one, then peel it off when you inevitably get air bubbles/dust specks under it while installing it, or when the display looks blurry and washed out.
Although matte films make displays look blurry, true matte displays are NOT at all blurry because the matte layer is right on the LCD. Both my MBP and my desktop LCD are matte, and they are as sharp as anything.
