That's probably my biggest gripe. If me and my gf both had one then sure, I'd send her a heart every now and then however cheesy it may be.
But the fact is, she has a Nexus 5, I have an iphone. Considering so many of the watch's features are dependent on the iphone, it makes a lot of sense to say that you're unlikely going to see anyone have an apple watch if they don't also have an apple phone. It's not a truly standalone product, it's very much an accessory working in sync with your phone. That means that the apple watch is a niche (smartwatches) within a niche (iphone owners, are relatively few) and so I doubt this will really take off. Like facetime. I've used it every now and then, but compared to skype, facebook calling, viber or indeed just text on whatsapp, it's a tiny tiny tiny part of my usage.
That's why I think this thing is gimmicky. Until every watch has it and it's just a third-party app that allows you to send messages between any platform, apple or android watches or anything else.
Do you think finger sketch messages will show up in iMessage on iPhone, iPad and iPod touch (and maybe OS X via laptop touchpads)?
Suddenly, hundreds of millions of people have it.
(If they don't do this, how is it going to deal with sending a message to someone who doesn't have an Apple Watch? Just show "(!) Message not delivered"?)
