The first one costs THB 14,900 (about $425) and that gets you a 5.5-inch FullHD Super IPS+ display, Snapdragon 625 chipset and a 16MP/8MP camera combo. Mind you, that price tag is on the top-specced version of that model (it's never easy with Asus' naming convention), which packs 4GB of RAM and 64GB of storage.
The Zenfone 3 ZE520KL, on the other hand, is more affordable at THB 11,990 ($345). You might want this one for more than the price, it's more compact with its 5.2-inch display (same tech, same resolution). Chipset and cameras are identical, but memory is not - the ZE520KL has 3GB of RAM and 32GB of storage.
The question that's most important to the rest of us not in Thailand - when the Zenfone 3 is going to be available globally - remains to be answered.
A shout-out to Niels for the tip!
Zenfone 3 with "5.5 inch Super IPS LCD screen, 64gb onboard storage, 3gb ram" variant(With a premium desgin ofcourse from ASUS) below 16500 INR, indian people will definitely go for it neglecting other competitor phones in this price range.
no more affordable asus phone like 2-series? :/
