Unicorn phone.
Just accept it, small size phone with flagship spec days are almost over. Just like hardware keyboard android phones.

Ok. Look for other phone

I'll say Lenovo is stupid if they try to merge their craptastic product with Motorola product.
Only advantage of Lenovo devices are the price compared to other devices. Their software & services are pretty bad. They still sell devices with Android 2.3 which I have no idea how they managed to pass CTS.

When Google took over Motorola they were in pretty deep shit. Too many products and the Moto Blur ...
Motorola under Google made an excellent turnaround. IMO they are in good path to be financially stable. Lenovo is inheriting Moto in good position. Whether they can produce another think IBM PC division-like success story it'll be up to them.

16GB is ok for regular users. For power users it won't be enough.
Learned my lesson with Nexus 4. I had to keep things minimal to have decent free storage space all time.
