"He says that Apple makes it "nearly impossible for 3rd party wearable developers" to create an experience that mirrors the Apple Watch experience"
And that is what the EU competition commission should really be looking at. Sorry but I have an Apple Watch and it is nice, however it is pretty much the ONLY smart watch that works fully with an iPhone, so you have little choice of which brand to buy and boy does Apple charge you for the privilege, I also question why it won't allow the Apple Watch to work with the iPad as being cynical, to boost iPhone sales or something?
BUT.... on the flip side Apple Watch does have good medical sensors and it integrates very well with Apple Health. I can't deny that works very well. Apart from the oxygen sensor that seems hit or miss.
I remember Pebble the first time round and was close to buying one of their watches, didn't in the end though.
