The Beo5 has not actually been released in the UK yet so it is tricky to say. It has a vast range of possibilities though and has some features not seen in most remotes. I would wait and see it for yourself before deciding if it right for you.
B&O is a premium brand and so is obviously expensive. It is made from high quality materials and sells from dedicated dealers. You can get similar quality sound for less but you are unlikely to get the same integration. At the end of the day, it is like buying an Audi instead of a Ford. Both will have similar performance but the owner experience is different. Nobody needs to buy B&O!!
