Aboard the GOOD SHIP LOLLIPOP, there's a Mobe and a Slab and a TELLYBOX

The Nexus 9 has a 4:3 ratio screen (or close enough) making it exactly the same as an iPad for watching video... letterboxing and all I'm afraid.

Yes, there is now Bitcoin-mining malware for Android

So, lets do the math...

According to the hashing rates here :

We could expect 1.3MH/s from a dual core A9 based phone like the Samsung SII. With a Samsung SIII that could probably go up to ~4MH/s (quad core, faster clock speed) and an S5 probably 8-10MH/s tops (Snapdragon 801 running at 2.5Ghz should at least double over an A9 at 1.9Ghz). All of this is contingent on optimising the program carefully for different CPU architectures (A9, Krait etc) and would require the CPU to stay awake and run at it's maximum frequency / voltage the entire time.

Using figures from here:

Assuming that you infected 1000 Samsung Galaxy S5's at 10MH/s or so you'd get 10,000MH/s which if you could somehow keep all the phones going for 24 hours in a row non stop (in practice they'd die in a few hours due to battery drain) would net you a whopping 0.33USD for that time period at current rates... in future that will go down.

So, 10/10 for inventive use of malware.... 0/10 for use of basic arithmetic!
