@Krisi, I agree about usefulness for most people, but I bet if/when Apple releases their version it will outsell everything else whether technically useful or not. The major "usefullness" of the Apple prodcut will be bling/status.
During the work week I am a safety manager, so any email could be something "serious," whether during the week or even weekends.
The verb you chose describes some of the hassle, "digging" the phone out. Perhaps my pockets are too small, or the S4 is too large. It is also anoying, and somewhat illegal, to pull it out when I am driving. With the watch it is still somewhat unsafe, but it is legal to see who sent something. Here in NorCal I wouldn't be surprised to see a proposal to outlaw looking at your "smart" watch illegal while driving.
I've been wearing a Pebble for just a year and it is close to "invaluable." I don't have to dig out my phone for each of the couple dozen emails and SMS I get every day, and the phone caller ID also gives me the early decision about whether to dig out the phone. I did have it linked up with Google maps but it was constantly giving me directions and that was very annoying.
The charger & cable are plugged in to my bedroom side table and I just link it up avery few days, probably 3 to 5 days. I don't keep track, and have not run it to zero.
Perhaps Pebble or others should evaluate a kinetic charging system like Seiko uses: moveable rotor charges the battery. In seiko's case it doesn't need external charging.
The "biggest" problem: the notification features are so useful that my other watches are languishing and I have to make a very deliberate effort to wear a Swiss analog timepiece on the weekends. when I go out, I have found it amusing that so many who don't wear a watch ask about the current time instead of digging out their phones: I guess it is easier to ask. It would be even easier if they would get them sleves a watch!
I am eyeing the smarty ring that was crowd-sourced at Indiegogo just for fun.
@AZskibum you said the right word "fashionable!" There is a lot of buzz in the fashion circles now a days (in particular San Francisco) on wearable electronics. In general these devices will be limited in their function due to power dissipation.
I've done an OS with footprint about 32 KBytes. It uses software interrupts for user API and can launch program from a SD card (or NAND).
But almost nobody is interesting.
People try to place Linux even onto the MCU. Linux is based on Unix, last, in its turn is dated by 1967 Year. Is it a progress in IT sphere?!
@AZskibum, all good points. Here's one question, though. Do you really think most people have actually abandoned waring a watch? I am one of those old-fashioned ones who still wear my watch. I recently heard my nice in her early 30's complaining that she's tired of reaching out into her pocket (or purse) to find a phone to tell the time. Sh wants a wristwatch for her birthday. I wonder if she is an exception...
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
