I agree. also, if they make the next nexus device 2mm thicker but give all that space to battery I'd be happy too. Although the "charge it every" thing works ok overall, having to constantly worry about my battery if I've browsed heavily or whatnot is annoying more than an extra 2mm and 50gr of weight.
That being said I have a galaxy nexus, and I own 2 spare batteries for it and I use those instead when I need to. not possible with the new nexus 4, though.
