This deal is ridiculous ...
Friend of mine had the Essential phone and eventually got rid of it after a few months. He went through 3 or 4 models that were super buggy and just not ready for prime time. He was one of the first people to get the phone, went in very early on the deposit, and went through the roller coaster of "Will it ship??" for 6months, or whatever, but was already in $1000 on the device so he stuck with it (he's generally like this with devices, getting in on weird phones/devices day 1). Eventually he sold it for whatever Nokia's newest handset is.
THey've probably figured out most of the issues with the original release now, so I'm sure it's fine, and for the price... if this is an unlocked price, that's insane. Even just as like a disconnected/wifi media player that's great (although, obviously, bluetooth/usb only, no headphones, but w/e)
