They abstracted FireMonkey's wrapper for hardware very well and you can take advantage of that. In my own case, I already managed to hook Asphyre into FireMonkey: in this case, FireMonkey does the initialization part, while Asphyre still uses DX9/OGL/EGL natively. This answers one of my earlier questions - yes, you can use Direct3D / OpenGL / OpenGL ES with FireMonkey without problems, if you do it nicely.
That sounds exciting.

Andru - from what I understood you do have access to accelerometer and gps and all those hardware bit of the ipad/iphone
