Here is an interesting article from CNET on the benefits of the Snapdragon 805.
6 cool things your next Snapdragon 805 phone or tablet could do - CNET
Personally, being the average consumer (maybe a bit more tech savvy than average?), if the g3 has the 801, I won't be buying it right off. I'll watch to see what it does. With all due respect to the more savvy techie types, I like the benefits of paying for a phone that is on the bleeding edge, rather than having a phone that is going to make me sorry I didn't wait.
Heck, why don't I wait for the 64-bit processing system? As a consumer, my wallet is the judge and jury and the control over how I manage it, is mine.
Speaking on behalf of the average and uneducated consumer, tech specs and promises of better performance do matter to me greatly, even if I don't understand the "why's" or the "trade-offs".
Attitude wise, I will tell you that the unconfirmed news of the phone having an 801 just took the wind out of my sails and put me back into the wait-and-watch-for-the-next-big-thing mode.
Sure, I'll give this phone a look-see when it comes out and I know it'll be a great one. Heck, I just bought my family (3 other lines) Galaxy S5's. THAT is a great phone too. It surely beats the Gnex for sure. Anything would be an upgrade!
When I buy a phone, it needs the "Wow" factor. That's why I bought the Droid Incredible and that's why I bought the Gnex. In its day, the Gnex had mucho "wow" factor, right brother Early? Remember? Heh. How can we forget? Good times.
My next phone will have to be exceptional, in every way, including the processor. I'm an Smartphone hobbyist, so much so that I was very much involved in leaking info on the Gnex to Android Forums and the rest of the world. I guess that qualifies me to have my opinions and tastes, huh?
In short, I've moved away from "must-have" to 'look-see" on this device. That's what my gut says. I generally go with my gut.
