I'm upgrading to a Mac that now fully supports Bluetooth 4.0 LE features which I couldn't use before so never did.
I have never used iMessage because I don't like being restricted to only using it with other iOS users and prefer Viber which is cross platform. The only time I did briefly use iMessage was inadvertent (every time iPhone is restored it turns itself on by default) and then when I turned it off I found that I LOST a bunch of iMessages which were not saved into the local message history - stupid!!
However the thought of replying to SMS on my Mac is sort of appealing.
So are there any catches to using iMessage? I note that I now have to link my iCloud and mobile number - are there any problems doing this and how have you found Continuity in general? Does it work as advertised and is it useful? Any other things to watch?
I'm using an iPhone 5S with a MacBook Air 2013.
