And to make room for a first-class cabin with lie-flat beds on transcontinental flights, JetBlue cut the distance between coach seats by one inch.
Has actual real-world consequences? Tsk, tsk.. The rich can lay sprawled out in their lay-flat beds while the plebs snarl at one another while standing ankle-deep in their own feces. We're back to the good old days of the Titanic.
Once Apple enters the field, the category will take off.
Your fanboism aside (given your faith), there are contingent realities that often have to be dealt with regardless of how many people initially and dutifully get in line before the glass cathedrals.
Exactly what is a bracelet / watch thing going to do in any meaningful way? Battery technology hasn't changed so forget having more than a few hundred mA available. That excludes speakers. Then there's screen size as well. Even with txt sp3k lol it's still impossible to do much with, at most, a 1" square screen. Unlikely text-to-speech can be handled with a flimsy processor (see battery size comment)
Then there's the style issue. Who wants to walk around with their Logan's Run hand implant? Sure, Apple will grant you a few color choices but it's still a stretch to think everyone's going to shell out $500 for a generic "steal me" wrist-wrap.
Some technologies just don't make sense. At least with our current battery and silicon constraints.
Always draw your curves, then plot your reading.
