Re: Ah, the frantic blinkenlights...
Sonos started off with a really good but limited range of products, namely a wireless mediabox (to play your source material, stored on a NAS, with your hifi system) plus another mediabox with a built in 2-channel audio amplifier, which did the same job, once connected by speaker cables to a pair of hifi speakers.
And it was all controlled by a funky handheld CR100 controller with a great display.
But they got a bit drawn into expanding their range...and by doing so, they stopped updateing the older firmware (they claimed due to limited memory in the devices) and for a while they've been marketing and selling a centre-channel speaker for TVs and a subwoofer.
They also love selling direct, undercutting those retailers who have supported the brand and the margin offered to resellers has always been pretty poor.
The lack of repair capability has also affected them, with customers being asked to return faulty products for assessment, and when told they were not repairable, customers would be offered a rather derisory discount off the full retail price of a new device.
So, what was once a great cutting-edge product is no longer leading the field and they've lost many previously happy customers due to their failure to maintain support.
