Indeed, and yes, I'm sure there will be a LOT in reality.
We here all understand this and is obvious and well known.
This would be like me buying a plant, not realising I had the wrong type of soil in my garden.
For someone into plants and gardens it would be totally obvious it would never grow there.
But hey, I saw the nice plant in the advert so I wanted one
Of course, there will be a LOT of totally non technical people who will find this out at the last second at the Apple store.
I would also presume this will be made quite obvious at the "Buy your Apple Watch here" website, that you need an iPhone for this product.
We may think it's obvious and funny.
But so far, the media adverts are very much glossing over this fact.
It's not like they are showing an iPhone along side it, with a statement like "The new perfect accessory for your iPhone"
So everyone totally got the message.
If anything, so far, it's almost being hidden.

You don't think it's possible that someone who does not have an iPhone, perhaps they like other phones for other reasons, might see this and also like the Apple Watch ?
