My view is this will be useful for me. And I realise it will not be useful to everyone.
Why?
1. Because I want something small that I can use to count my steps (I try and do 10,000 a day) and the watch will tell me this. I will not need to take my iPhone out with me for the steps to be counted. I do not need to know where I have been (therefore I do not need GPS on the watch) as I will have just been there. I realise some people DO want to know where they have been on a map and that is fine. But for me, it is about how far I have walked / calories burnt etc not the route I have taken. I did once have a GPS watch but found it more useful for measuring how far I'd walked not WHERE I'd walked.
2. I want to listen to music during my walk with the dog and having the storage referred to gives me 200+ tunes to listen to with bluetooth earphones. More than enough for 10,000 steps.
3. I always wear a watch for telling me the time / date. Tick.
4. I actually do not think the watch I will purchase (£339) is expensive compared to some models of watches I own. And given what I have said above, the

Watch will do much more that will prove to be useful. Would I pay £600+ for a watch? Probably not but hey - I don't have to.
5. In addition, I work from home and having the watch with me instead of carrying around my phone in my pocket, whether upstairs, in the garden etc, will be very useful. Including for counting my steps, answering messages, quick calls etc.
6. I sometimes use the treadmill in the house and at the moment to count my steps I have to carry my phone. Now I can leave it downstairs and use the watch, whilst still listening to music through bluetooth headphones (and of course still receive notifications).
7. I like the idea of directions when walking on the watch - when we travel I will be able to use directions on the watch, and keep my phone in my bag instead of carrying it in my hand which sometimes isn't a great thing for security reasons. Again I will also be able to receive notifications without taking the phone out of the bag.
I consider the watch will allow me to use the phone less and less.
So for my money the watch works a treat.
Just my two pence worth.
