So I had a slight setback in War Worlds development last week... my house was broken into and all my test devices were stolen! Luckily, they didn't take my main development PC (even though all my code and such is backed up to the cloud, it would still be a much bigger pain if I had to rebuild my whole development PC!)
They took (amoung other things), my old Samsung Galaxy S (which was my "low end" device), a Nexus S and my Motorola Xoom (which I was using to make sure the game ran OK on a tablet).
I still have my day-to-day Galaxy Nexus, but that's a pretty high-end device and I normally use the low-end devices for regular testing to make sure I don't do anything stupid performance-wise.
Anyway, for now I'll stick with using the emulator and maybe someone at work will have an old phone they're willing to part with. The show must go on!
