On Windows, SDL will use DirectInput 3 IIRC. The last version was 8.

I'm still pretty new to directx and I read there are major change between dx 9 and dx 10 but all I found on google is unified shader. Can someone briefly explain to me if there are other differences.

First and foremost, DX10 is Vista only. That may limit your decision to program with it depending on your target audience. Beyond that, the differences get pretty technical but the basic idea is that DX10 is a complete re-write of DirectX to take advantage of newer hardware and driver models. This makes it very different to program in than DX9 or any of the previous versions. Some of the highlights are:

* No fixed-function rendering. You MUST use shaders in DX10 (not a bad thing, mind you)
* Addition of geometry shaders
* Shader uniforms built and passed as buffers. Lets you use them like textures or vertex buffers.
* Heavy emphasis on render-to-surface. Even your main window is basically a texture that you render to.

Overall the changes streamline the process greatly, though you will still see a lot of complaints about the API (Primarily because of it's ties to Vista). What it boils down to in the end is that you should use DX9 for older hardware or OSes and DX10 for newer hardware on Vista and up.
