Gimp the camera? HELL NO! The camera is the one thing we can't change. I can always plug my phone in but I can't fix a horrible photo. The Nexus line has always had atrocious cameras. If Google doesn't change that I'm not buying the phone.I know, but please don't gimp on the battery of all things. If the G2 has a 3,000mAh battery, and the N5 is based off the G2, then keep the battery, and gimp the camera, no LTE, with HSPA+ being fast enough for me at 42mb/sec and even go 720p screen for all I care, but battery life is #1 most important feature.
I think Samsung's success has pointed out that the screen is the most important feature in a phone. Toss in a great screen and camera and gimp everything else IMO.
