LG makes good hardware, their main problem was always their UI.
But with pure Vanilla Android, this is taken care of 100%.
4.2 seems to have some sick features, like Photo Sphere.
It sounds REALLY wicked.
Btw, the Nexus 4 comes in the 8GB and 16 GB variant.
I know, it would be nice to have an sdCard slot, but so far I have been doing OK with 16GB.
I have currently the Galaxy Nexus. Great phone, but it seems I will pass it over to my mother and I will get myself a Nexus 4. That S4 Pro is gonna be fast supposedly, wonder if will in fact beat the A6 or Exynos.
Also the Nexus 10 tablet looks sick, and will probably cop me one too later on though. To me, if you want android, Nexus is the way to go.
I had an HTC Amaze 4G (CRAP!) and HTC MT4GS (FAIR), And couldn't stand HTC Sense and I always has issues with their terminals. DONE!
Can not talk about Touchwiz but it seems much better.
Make Xtratime great again.
