You’re entitled to your opinions of course, but this is a weird one: you buy into a (great) piece of software, then come in fuming about ‘missing features’ that were never claimed to be present in the first place.
Roon does what it says on the tin – and that’s a lot. While playing audio to iOS devices is definitely on the radar, as well as remotely streaming your Roon library, it makes no sense to complain now. Roon has made remarkable progress over its first year of existence, but anyone becoming a member (whether yearly or life) did so based on the feature set available at the time of purchase.
Roon will continue to expand its features as it has done in the past, but no promises were made on the timeframes of these specific two.
