I was about to buy an android tablet because I want to tinker with the Mobile app. I'm an iPhone user so I don't have a current 4.0 Android phone.
I decided to take a peak online to see if there were any windows apps that could run .apk Android apps, because I have a Windows 8.1 Tablet (yes I'm fully aware the tablet can run the full version of ARC....but what I want is to test and tinker with the Android mobile app because my desktop computer typically runs ARC).
Anyway I found this nifty piece of free software called BlueStacks. Once installed it allowed the Mobile app apk to be installed and it runs! 
Just wanted to share incase anyone else is interested in running the Mobile app on their Windows device.
Yes, bluestacks is pretty good. I've not used it with ARC yet but have it installed ready to go. Good news that it runs, that'll make things easier when I get to playing with the mobile version (although only easier in that I don't have to find my phone, make sure it's got power etc. etc.)
BlueStack has me impressed! It's nifty for sure. I just wish there was a way to run the mobile version on my iPhone.
