Once you have ripped your entire music collection to your PC, you are faced with the problem of listening to it around your house.

The Sonos does a pretty good job - stick a white box in each room and you can stream different tracks wirelessly to different rooms.

The wireless controller features a good-size color screen and gives you access to all your music, and it is one of the few non-Apple things to feature a scroll wheel.

Sonos also gives you access to internet radio from round the world, and ties into Napster, meaning you can play pretty much any song in the world.

It also lets you get at Last.FM which introduces you to other musicians you may like. It does this by “scrobbling” (taking note of) the songs you play to further educate the service on your tastes.

It is an expensive option for getting music round your house, and sometimes the internet connection can drop, meaning your online music services can go deathly quiet.

But once you have got it, it is hard to understand how you lived without it.
