The cost and power requirements in 4k screens vs 1920x1080 are huge, for fairly little advantage. See the recent Intel discussion where such a screen cost ~four watts more than a standard-resolution one, both without FBC.

As for the storage i prefer a 256GB (or more) pci-e ssd.

The built-in battery is much more about maximizing the size of the battery than profit...or at least you can make that argument as easily since samsung doesn't seem to charge less for their flagship phones than htc.
What do you mean "The hw requirements on my Android for calendar / email are much higher than on 64-bit desktop"? Even the highest end arm chip is about half as fast (per core) as four year old i7-2500K (completely ignoring the 32/64bit distinction as that's not too important for this purpose).
When it comes to CPU perf comparisons, I don't think i5-2500K (2500k is i5, 2600k is i7) is only twice as fast as ARM chips per core. 2500k goes up to 3.7 GHz, many high end ARM cores are 1.6 - 2.0 GHz. When you run traditional single threaded code, x86 has better branch predictors etc. When you need power, it has 256bit AVX. It also has faster buses and memory controllers. You can't really compare apples and oranges.

Surely an app like email client has some fixed hardware requirements.
What's the point in adding more and more bloat if the hardware is fast?
Consider something like sylpheed or claws mail. I've used both. They have tons of features unlike the standard android email app, which is very minimal. These email clients (at least the statically built version) use only few megabytes of memory. Meanwhile Android email app uses tens or hundreds of megabytes. It's funny cause the Android app has much simpler gui toolkit, the VM is designed for low end hardware, it has much less features. It's like 90% less features, 900% more size. Very bad tradeoff.

Regarding branch predictors, that is an area that was hugely improved in the most modern arm cores (a17/53/57). It's difficult to say how it compares to intel but my looking at benchmarks arm has done a magnificent job with far fewer resources.
NEON is a the simd alternative for arm has 32 64bit (128bit for aarch64) registers while haswell's registers are currently 256bit but no idea how many they have. NEON has also had good support for integers for a long while (still doesn't have gather, though). The numbers I found were: haswell 32 sp flops vs a15 8 sp flops (probably doubled for aarch64).
The new bus krait design on snapdragon 805 actually has a very wide and fast memory bus (2x64bit at 1600MHz, so as fast as haswell). Memory controllers have been a big weakness, but have gotten hugely better starting with the cortex a9.

Perhaps, focus more on OpenCL to work towards an HSA enabled solution?

Also, the first LibreOffice version was numbered 3.3. We've never released a 0.1 version.
