Nice, but when I see something that's labeled "Only 3.5 MB" or worse "Only $29.99" I'm actually less likely to click a given button. This is probably because this kind of language gives me doubts about the intentions of the site owner, since it's marketing speak. And it challenges the viewer's brain to think twice about whether the price tag actually deserves the label "Only". A better alternative would be to just present the facts and leave the hyperbole out entirely.
