Aiya, they is no end if you want always having the latest high end device.

You already using Galaxy S4 which is top model also, remember a lot still using Galaxy S2 or even one of my friend still use Galaxy S - first generation of Galaxy!

Another 2 to 3 months, something will also replace this Z Ultra as the highest end flagship. Nothing can be forever in top.

I just played wit z ultra just now, i was suprised it was so huge than i imagined the display was superb, better than my xperia tablet z n ofcoz far superior than xperia z phone. It was really like the size of my nephew tab 7.0. The metal frame also make it more premium feel. I cant wait to c how honami will look like
?

Ya, it is awesome and screen much better than tablet Z.
I rate 10 star out of 10 for Xperia Z Ultra screen panel.

8 star for Xperia Tablet Z

5 star for Xperia Z.
