That's what I was thinking but I suppose it depends how big the ad is going to be, also what laptop is that? Looks a little dated to me (maybe wrong) Can you not find a more modern looking one, a nice mac or something?
Not being unkind but it looks quite flat and if I was looking through a magazine I probably won't look twice at this, maybe not even once. Nothing is grabbing me here, why should I contact you? At the moment its only saying as much as your business card would.
