I'd be prepared to accept a six monthly charging cycle (still ten times more often than regular watches) but every frig'ing day is ridiculous.
Ah yes, queue the "but my Casio ..." posts that plaster every smart watch thread.
Are you really having that much trouble getting over the word "watch" in the name? It's not a watch. It's a fairly powerful computer that happens to be in a watch form-factor. Do you hear the word "watch" and just shut off your brain after that? It's called a smartWATCH because calling it a "wrist hobblinsnicker" is poor marketing. If the only possible thing you can imagine using a smartwatch for is the same things for which you use your Casio, you are right, buying one would be friggin' ridiculous.
If you don't want a computer on your wrist, that's fine, but making comparisons to your Casio's battery life is about as smart as making a comparison between a calculator and a laptop computer. I mean really, imagine those idiots. A handheld calculator can multiply numbers just as good as that desktop and costs hundreds or THOUSANDS of times less. It NEVER needs to be charged. It fits in my pocket. It doesn't need a full keyboard with all of those useless letter and function keys. It has a built in display saving me hundreds of dollars. The OS NEVER needs upgrading, and it never, ever crashes.
