If Apple's 'watch' is anything like this in implementation or design, then I will not be interested.
It is bizarre to launch a watch whose battery life lasts "about a day". You need a watch all day and then some with heavy usage allowed for, or there is no point. It is not like a phone or laptop where you can just plug it into a power supply and accept that fact.
It need's to not look like this, not be so bulky and last for day's.
But what do you expect from such a small device?
If you think about it, Apple has already tried this with their iPod Nano, so I don't know why people are expecting anything more than what Samsung or Apple has already done.
All these watches are only good for the following....
1. Time
2. Weather
3. Fitness (Health Monitor)
4. Quick link to your phone for calendar/email/sms etc
5. Music
Anything else is a pipe dream. Samsung has covered all of these but went overboard with a camera/video device. Some people may want a front facing camera for Facetime or Skype but it would take up so much valuable screen space making it impossible.
Battery life is ALWAYS going to be a concern with such a small device and a full watch size screen. You will be lucky if Apple can extend this any further than what is already possible.
The Galaxy Gear doesn't look that bulky once on a wrist. It's comparable to a Pebble Watch. Flexible glass is still years away for something like this so Apple's iWatch will also be just as bulky, or just a tad slimmer.
I'm not trying to shoot you down or rain on your parade, but you have to be realistic of what is possible right now in 2013. In 5 days time we will find out what Apple has up their sleeves, just don't be too disappointed when it's not what you expected.
