Again, I don't think its Apple's concern what you do with the watch after you buy it. No if you resell it you won't get as much for it as when your bought it. But that's not Apple's problem.
If we use your scenario, that in one year the watch will be so much better (but still supporting the same bands as gen 1) then perhaps Apple will allow people to trade in just the watch face for a new one and keep the band(s) they have.
Bottom line: I dont think Apple designed this product around 'how can we make sure people get the most $$ possible if they choose to re-sell it a year or two later'.
Yes, but you can see my point and my logic I hope.
Note: Many people don't like using Apple's trade in scheme as naturally people often want as much money as they can get from an item, and that usually means a private sale rather than what Apple will give you.
I hope you can see, if "YOU" bought the stainless version, with say a (let's say) $300 loop band.
If that is the ONLY band you get.
When you come to sell it, if you love the band and want to keep this, you can see how, for you, this is now difficult.
If your Stainless steel watch did come, as standard with the rubber strap (it was built into the price of the watch) and your luxury loop optional extra strap was in addition to the rubber strap they all came with.
How much easier it would be for "YOU" when it came to upgrading time.
I'm not saying I'm right
I'm just putting forward this as a good scenario for everyone.
The other way to get around this, would of course be to buy 2 straps when you get the watch in a couple of months time.
You buy the watch.
The luxury band you want.
And you also buy the rubber band to be able to sell the watch privately later on without losing your luxury one.
And yes, you are right, Apple don't care about you and the future, They wish to sell you the watch for as much money as possible, and then they will work hard on the next model, in the hope you will sell the old one and buy the newer next model so they make more money.
That's business
I'm just pointing out, as the strap will cost them about 5 dollars to make, that 5 dollars could be build into the price of the watch, so everyone in effect buys the rubber strap by default.
You may be right however, and they feel they may lose sales if they did that.
We will see soon enough
I think, the most important thing we are all wondering about is how they will handle the new models in another year or so.
Many seem to be expecting they will change the business model they have used for years / decades.
Or they may just do what they always have done, offer you a new improved model, offer a lowish priced trade in for your current model and just let you decide what to do.
