Okay, I'm getting the 30 Mbps (approximately) that the ISP is claiming I'm getting (and for which they are charging $62/month!). However, just how much faster is it than 15 Mbps? For $15/month less, I will only get the 15 Mbps, but how actually noticeable will that be to me, the regular user, the casual surfer who doesn't download a lot of video, streaming or otherwise?
