[Sony Xperia Z Ultra] LordManhattan:
I personally love Readmill. It's cross-platform, so you can get it on iOS too, and it also syncs between devices (i.e start reading on your iPad and resume on your [insert device]). It's a nice app if you have epubs etc. stored locally (on SD card/internal memory), but it doesn't have a large in-app store if that's your thing.

Regarding the One Max, meh. It's big and all, but it's hardly a phablet. It's more like a big phone and it's exactly like the One, but bigger. No special features or anything. The Ultra on the other hand is a phablet with a big P. The UI is properly sized for its screen size, while the Max' UI is just blown up. Again, it's a large phone.

I'm having some "issues" with my Ultra though. You've probably read my post about the screen acting up when it's cold outside. It doesn't affect its usability though, but it just looks weird for a minute. I haven't read about anyone else having this issue, so i'm assuming it's a production error from Sony's side.

Battery life is pretty good. I didn't expect anything amazing since it's so thin, but i got properly surprised. Here's a screenshot from yesterday. I watched tv shows all day, watched a movie (Bad Grandpa), browsed, read some news (with Press) messed with some camera modules and so on. That's how long the screen was on, not the device itself. Not bad for a 6.4mm thick device with a full HD display. It'll last even longer if you're big on reading ebooks. It tends to only drop about 1% from i go to bed to i wake up (8 hours) with Stamina enabled (cuts apps' data connection while in standby, unless you whitelist some apps).

Camera? Don't go to a Victoria's Secret party expecting amazing photos and memories. They'll probably end up looking like manatees. Fine, it's not that bad, but there's a lot of noise in them, so it's absolutely not the go-to camera if it's a little dark, or even dim. It performs okay in daylight though.

Screen? It's really good. You're not used to AMOLEDs(?) since you're coming from an iPad, so it doesn't have the deep blacks, but the colors are much much better and more true to life. I don't think you'll have any complaints.

Audio? It's not a boomblaster, but it does its job (for me at least). Most people tend to forget that the built-in equalizer has an option called "xLOUD" and it'll boost the speaker volume. It's really loud (for me) when xLOUD is enabled, and i have never ever pushed the volume to max.

Software? I like it. It's stable and fairly lightweight (compared to TouchWiz and whatever that 10 year old designed for LG) and very fast. It has "Small apps" which are small floating apps, that floats on top of whatever you're doing. Writing an email and want to check the curling score (go Norway!), hit the multitasking button and hit the "small browser", and BOOM! A tiny browser window opens up on top of your email, and you're free to read about Canada's loss without leaving the email app.

Yes, i'm the guy who only want to share or say one short thing, but goes way beyond that and writes a novel. I wanted to mention Readmill, and look at this.. it's the work of a madman (@shaolin95 totally knows what i'm talking about). Sorry!
