Although I am beyond 40, still feel young... you buy B&O over time. Just got my BS5/BM5 last weekend and the ease of how it integrates into an existing link system, the ease with which it integrates with your PC... marvellous. I am not a "techie" that's why I enjoy B&O.
On another note. Over the years, I have been working in different countries and have bought my B&O equipment in different cities across Europe. You always get excellent service, there is always a very competent technical support and even when some elements of your B&O equipment are beyond 10 years, they don't show you the scrappage bin...
I think BS5 will sell great, with the regular software updates it will stay up to date.
