<p>Is it worth buying?</p>
<p>I had no idea this was out there. That sounds cool. I would like to know if it's good too.</p>
<p>I don't really think it might be that helpful ! (I don't know why! may be I've a bit of technophilia!) TO me, technology stuffs like this will have a limitation (not that books don't!) Well, it may depend on what u want! If u r flexible to study on a monitor u might want to check out that "costly" product!</p>
