Playing with Android Studio and iPhone simulator this week, to get an application ready for source code review without having to release the code itself.

As usual the code within android is a bit messy, whilst iOS code is absolutely clean and easy to read. What I expected.

Running the android emulator without Intel HAXM acceleration is horribly slow.
No problems an absolute comfort on iOS with Xcode on the other side. (admitted that iOS code is being compiled to native x86, so this is quite an unfair comparison)
