it is useful - I do read a lot of text on my phone - books / and web.
its one of those features you don't advertise though. I mean I wouldn't buy a device just for this but small things like this make people miss them when using another phone / platform. I guess its not the big stuff that build the brand loyalty but these subtle details.
If you're reading text, don't you have to interact with the device to scroll/page the text? Or do Samsung phones have some sort of absurdly low timeout? I could imagine this feature being useful if the screen typically locked itself after, say, 20 seconds of inactivity, but a much better solution is to simply increase the lockout time to something reasonable.
