It's a G4 and it's almost that much. The 4K camcorder is amazing. So maybe it is worth all that. Given what I'd have to pay for all it does in other devices, yes, it's compelling.
The LG G2 was evidence that the OEM was trying to go places the smartphone market. The rear power/volume rocker was a radical design move has been LG's signature feature for the G series.
The newest kid on the block, the V10 holds true this design choice along with a quirky new notification display and manual photo options.
A Snapdragon 810 processor, 2K display and metal trim doesn't warrant it's $700 pricing. Sure, the V10 has the sex appeal of a runaway model but there are other options currently that offer similar features for less. (i.e Nexus 6P, Moto X Style, Galaxy S6 etc).
Please waive your options for deciding on this compelling yet pricey device.
