content: I did not research this one because I was happy with my previous palms. The screen in the ads has the night light lite so it appears to have backlighting which is does not. You have to have direct light to see the screen.You can use the light to make up for the darkness but it runs the battery down quick.To add to my sting. The m515 came out 3 weeks after I bought it.I will probably get a Clie or a Handspring the next time....
