agreed! what the use of a phone when it has the superior hardware but cant even be running on JB. this i LOLed hard at SONY. Samsung and HTC realised this and hence they are trying their very hard to update the older gen phone
cant be said of SONY. even though they have the closest working relation with JBQ, but their software look dated. nothing new to the game except for better spec.
the reason im attracthed to Z is that i can foresee that this will prob a dev friendly phone as more dev is abandoning exynos based phone project
if it is more expensive than note 2....SONY is digging their own grave.
