[Sony Xperia Z Ultra] Benjiro:
I agree with the rom. At first i was also thinking, to switch over to a rom like CM. But after running the Ultra ( what i only got yesterday ), my conclusion is very clear: There is really no need for a custom rom. Remove some crap programs that are standard installed, get some better versions from the Play Store. And for the rest, its perfectly good.

Unlike custom rom's, where you have a lot of small "incompatibilities" because the Rom's are in general made with multiple / different type of devices in mind, and where you end up with a rom, where your device is a "afterthought". They work, but may have small errors, problems, etc, that you end up wasting too much time on actually fixing the rom, then just enjoying the device. *lol*

For months i was looking around for a "bigger" Phone/Tablet, coming from a now 4 years!! old HTC HD2. I got fed up with the small 4.3" screen, squinting my eyes all the time, or forced to "zoom in", making it disorientating after a while ( especially with threaded comments on some sites ). And my 10" tablet, is to cumbersome to carry around all the time.

My eyes first fell upon some of the small tablets, but ... no phone ability, and most of them still to big. And still need to carry 2 devices around *uch* ... Then i started to pay attention to the "new" Note 3 ... looked good. But did not like the price. 550€+ here in "promo". By chance i stumbled over the Sony Z Ultra on ebay, where some people had bids going on. I already knew that some people probably ordered the "phone", and did not expect it to be that big, so they sold it again. Less of a problem for me as the size is more ideal. So i entered a low bid... and actually won ( 350€ ) for a second hand one. Poor baby, mistreated by its old owner ( smoker ).

Now its right next to me. And its perfect for media/browsing/etc ... Will i use it as a pure phone. NO!! Who the hell still uses there phone as a "phone" on regular basis anyway? :)

Installed WeChat ( so can use it to contact my wife/family when needed ). Linked all my accounts. And voila. A computer away from home, that actually fits in my jacket. No more need to squint my eyes. And i can still in emergency "call", or be called.

Plans for the future: 64GB SD card, probably a 4000 a 4500mAh Battery Case ( in all honesty, its so thin that i something fear breaking it! So i like some reinforcement ), hopefully with a Stylus. And my plan is to turn this device in a Filofax ... Extended battery, Stylus, big amount of space.

No way that is possible with a Nexus 7 ( too big ). The Note3's screen in all honesty is still to small for me ( and the price is also a factor ).

My only worry is the not replaceable battery. As i like to use a good device for years, so i hope in 2+ years, the battery is not going to be a problem. But have already found only reviews of people being able to open the Ultra and chance the battery ( just takes a bit more work ).

Only bad thing: Why a 8M Camera, with no flash... And default ISO setting of 400!!! ( in Auto ). Terrible. My wife was instant disappointing seeing the Camera. For the rest ... perfect device for me.

Think for most ZU owners, that we are a niche market. People who want tablets that are phone's also, but also pocket-able, but no small screen, and no weak system. The Q800 really rocks on this ZU. That will be future proof for the next few years, that i am sure about. And given how popular the Q800 is, think there will be a lot of developers support / optimizing software for it in the future. And with Google looking at a better Run-Time / Compiler ( 4.4 ART ), looks like in the future just with a new rom, the "speed" will be even more enhanced.

Now, that leaves one question: What to do in the Summer!! *lol* Lucky where i live, there are maybe a few months of sunshine, all the rest of the time its jacket time *lol*. But yea ... in the Summer ... who knows ... *lol*
