A comic called The Joy of Tech suggested this week some hilarious features for an Apple iWatch.
I have some predictions that are less funny but more likely.
The Apple wristwatch rumors have always been associated with the idea of curved glass. But why?
With such an aspect ratio it would have to curve around the wrist so its edges wouldn't rise absurdly above the wrist.
I'll go further: I think the perfect size for the watch's screen is exactly 1/4 the size of the iPhone 5's screen — or half as wide and half as high, allowing two columns of icons stacked three high (six icons per screen). That would enable standard iPhone 5 apps and videos to be displayed by being shrunk in half.
I believe the Apple wristwatch will have a physical button, as iPhones and iPads do, to prevent accidental activation of functions.
The best way to picture the Apple iWatch is to shrink the existing iPod nano just a bit, making it a little smaller and thinner, then wrapping it around the wrist with a rubber or leather band.
That size would also be small enough to be reasonable for men, women and children to wear.
And most importantly, the Apple wristwatch would have to break away from the ridiculously bulky designs that nearly all so-called smart watches have suffered from to date.
Hardcore Apple fans wore the previous-general iPod nano as a wristwatch (including Yours Truly). But that was an awkward accessory with sharp corners that stuck way out.
Apple is obsessed with shipping the thinnest phone, tablet and even desktop all-in-one PC — you can be sure they will be obsessed with shipping the thinnest smart watch ever.
It's almost certain that the watch will perform all of the functions of an iPod nano without a Bluetooth connection. In will show the time, play music and videos and offer some fitness-related Nike app functionality out of the box. It will be designed to be usable by runners and other fitness fans.
But it's also nearly certain that the watch will interact with a nearby iPhone via Bluetooth 4.0, displaying incoming iMessage items, giving you alerts of all kinds and allowing you to control basic functions on the iPhone without removing it from your pocket or purse.
In other words, the Apple watch will be both a stand-alone iPod nano and a peripheral device to an iPhone connected via Bluetooth.
At some point, possibly even in the first version, I also believe the Apple wristwatch will probably allow two-way voice — you'll be able to answer calls by talking and listening to the watch like a speakerphone. It will also enable Siri commands via the iPhone.
These are the facts about what we know and what we don't know about the Apple iWatch, and also my personal predictions for how it will look and function.
