...and the Sonos just works, always... period.Except for those people who post to the Sonos forum asking for help because their system doesn't work. ;-)
Seriously, I've been involved with both computers and music reproduction systems for a very long time and no option is guaranteed trouble free.Sonos has tried hard to make their system easier to use, albeit at a higher price and with reduced flexibility in certain areas compared to other options, but you still can't pretend that some users aren't going to have difficulties with setup and operation.
The best bet is to find stores that sell each of the products you're considering and get a live demo.
