Hate to say this, but I think people are being just a tad bit greedy on this topic.
Both the new version AND the original nexus 5 are great phones and the reason they are redesigning shows how Google is totally committed to the quality of their product.
Google is a relatively new phone manufacturer and like many other things they do, they do it differently than most other manufacturers.
Yes the speaker sucks... But I paid $50 for my N5 on a two year contract and the LG G2 would have cost me $300 and they definitely are comparable devices.
Despite the redesign, despite my speaker being sub-par, my nexus 5 is still amazing. It literally has a faster processor than my laptop.
The rate that technology changes is exponential but is it really fair for people's expectations to be changing that fast as well?
I love Android and I think it's great what Google is doing with the nexus series.
Just my two cents.
