Wearables...priced as tech or as fashion?
What are you willing to pay?
If a manufacturer of your chosen ecosystem managed to produce a device that successfully met the promises made, whats a good price?
Is it the price of a cheap, middling or expensive phone?
Is it fair to have a generations, with yearly (or sooner) devices?
Should these devices be designed with fashion artist?
Should these devices match the fashion of the time or be as neutral as possible?
Is it fair to have generations? Only if there was a big flaw that required hardware changes or if it was a new design (ex. Pebble Steel). Otherwise, I think it should be almost purely software updates.
Fashion artists? Yes! Very much so! One of the main things I didn't like about Pebble was its looks. I love the watch, but that plastic body was kinda bad. The new Pebble Steel is much more to my liking, though I don't really want to upgrade just yet.
Generations should be at least 2 - 3 years apart, for hardware at least. Software should be updated yearly, but having hardware revisions every 2 - 3 years you're guaranteed more reason to upgrade. This period, however, is long for a company to maintain sales between hardware cycles, so my suggestion would just be to make money of services and apps. Still, I don't think wearables manufacturers will find much profit here.
Appearances should either be really nice or made in conjunction with a famous fashion brand, with a cheaper edition that is made of less expensive materials and has a less ambitious design.
