I am interested in any suggestions...

I have been wanting to upgrade/replace my HTPC for some time, but in particular I want to move away from using Windows and instead use Android as the main OS....

I have also been searching for Android based car audio, a double din touch screen.

In the end, I want to be able to network all these devices so they can all connect to my home WiFi network, and I can moves files and download/install apps as required.

I have found many Android car audio, all either unbranded or unknown brands though, so am interested to know if anyone here knows of anything or recommends anything...

The HTPC is the biggest problem....
I am wanting at least 40 inch TV, prefer bigger....but I want the computer all built in like an all-in-1 pc.
The biggest all-in-1 I have found is 27 inch.
I can of course buy a standard tv, and have the htpc separate...just not as nice, and not a challenge.
And having Android as the OS is also problematic, as not quite yet mainstream...
What frustrates me, is Android is the OS on many mainstream tablets and laptops, so why not a desktop pc?

Any help or suggestions would be appreciated.
