Many people would be delighted to get that download speed. To give some meaning to your figures, use the test here:
http://www.speedtest.net/
When the test is complete you'll see your upload and download speeds in the central box. They'll probably be similar to the results you've already got, so they won't tell you much. But take a look at the other box, at the top left of the screen. That will tell you how long it will take to download typical MP3 and video files (which, to most people, is far more meaningful). Then click, at the top of that box, on 'View Upload Speed'. You'll be shown how long it will take, for example, to send an email with a 1Mb attachment. Then click on 'Your Summary', at the top right of the screen to see how your figures compare with the averages achieved by other users of the site.
I can see no real reason why you'd need a higher broadband speed for normal domestic use. At least you should be able to beat a carrier pigeon anyway!
