For some reason, internet access isn't considered worthy of much regulation by the US government yet, so a majority of users connected to the internet here are people like me who still don't have unlimited broadband internet. And unfortunately, while 120 megabytes isn't considered to be very large by today's standards, it's still a large file to download.

Personally, we have a lot of people living in one house, sharing one internet connection, and our monthly data plan usually gets used up pretty quick. We tend to avoid files that are greater than 100 mb in size.
