My guess would be most people have dial up at home and high speed at work where most of the downloading occurs. One of the advantages of a DSL is the phone line is free and it is on all the time.

However there are disadvantages associated with the DSL that is hackers tend to seek out these DSL connections because of the available bandwidth and ease in connecting. This could be solved through the use of firewall protections; anti virus protection. and turning off computers when they are not in use. Also the connection is faster for receiving data (downloading) than it is for sending data (uploading) over the Internet.
