Seriously, why do you need 1920x1080? 1280x720 on a 5 inch display is great, even 960x540 on a 4.7 inch display (Optimus L9) still looks great, I just don't see the point unless you want to deplete your battery as fast as possible...
Yes, Enough with the PPI race. On a 4" or 5" display give me 720p and more battery life over 1080p.
If the manufacturer does not opt for the top of the line GPU, games suffer too, since by doubling the resolution, you need to quadruple the pixels rendered. Apple made this mistake with the iPad 3 and iPhone 4, both which performed worse than their predecessors.
This PPI race reminds me of the megapixel race in cameras. Where dumb consumers think a "higher spec" is better when it actually gives them a fuzzier screen (pentile OLED over non-pentile, not in LCD), worse battery life, and worse performance in games.
