I'm not absolutely getting it by any stretch yet, but definitely keeping an eye on it. I'm in the opposite end of the spectrum from Overstew - I've never owned/used an LG phone at all. However, I'd been thinking heavily for months about moving to a G4, until news started coming out about the G5, so I'm intrigued enough at this point to see how it actually turns out after all the reviews start pouring in.
Value/depreciation on a phone seems silly to me, as I (at least thus far) don't switch up phones any more frequently than a year and a half or so at best - and that last time was only because my Photon Q had a whoops-ident whereby the screen cracked and I had to have an immediate turnaround for work purposes (that's how I ended up on the S4). Also, particularly given so many people seem to require cases that cover the majority of a phone's outer housing anyway, the whole 'cheap' vs 'expensive looking' argument is a pretty silly one to my mind as well.
