Have you tried any of the other smartwatches? I ask because I really really like my LG G Watch R. The specific use case you mention - I don't use Hue, but I have a Roku remote installed on the watch that I use all the time. It's two taps to get to the remote. Much faster than pulling out my phone. I also love that it looks like a real watch. Most people that see it assume that it is just a regular watch, unless I start talking to it. Maybe I just have poor taste but I really don't like the look of the iWatch - it looks like they shrunk an iPhone and strapped it to a wrist band. Which I guess is what it's supposed to look like but not really my taste, I guess.
Not trying to bash Apple here I almost always recommend Apple to friends and family even though I mostly don't use it myself, but I do think there are much better smart watches available than the iWatch.
