For what it's worth, other than gaming or CAD applications, I can't see the need for anyone to need a computer faster than about 1 GHz.
If you really want to suffer, come to my house and work on my wife's webpage for me... I have about 10 more MB of data to retrieve from online and 20-30 MB more data to upload......
ON DIAL-UP!
Or, essentially, the 30MB that I have to deal with is going to take hours longer than the 15 minutes you're whining about.
P.S. If you have a hobby or something else to do, you can always keep busy while those big jobs are running...
