No 4k video recording. --> imho, overkill for now. not many TV is 4K, so, even if we record it, can't really enjoy playback anyway...
No NFC. --> kinda surprising but well, right now, still not a deal breaker, though mobile payment is going to be an IN thing...
Not Glorilla Glass. --> recall reading... it was mentioned that they sourced for alternative glass but with somilar GG protection. still, ya... everyone still like to slap on a TG SP these days...
Charging from 0% - 100% took about 3 hours --> this is kinda surprising. i thought there'd be "quick charge"...

quite sure most, if not all, signed up to be explorer...

well, i don't think got NDA.... so... any explorers here?
