Can this be used in a project to replace/emulate the Squeezebox Touch ????

You can do it, using piCorePlayer

Now you can get and ApplePi DAC system that is completely ready to go out of the box, and includes a 7" touchscreen.

Picture:


Here is a video showing it in action:

Hello, Leo.

I have some questions for you:

1) Is this compatible with my Mac Mini (Apple Computers)? Is this compatible with my iPhone or iPad?

2) Eventually, the touchscreen will die or malfunction (most likely before the Pi suffers indignities). Is the touchscreen user replaceable?

3) Eventually, the touchscreen maker will stop producing this unit, what options would I have if my touchscreen dies after it is no longer available?

4) If I back this product only to discover I don't like how it sounds, may I return it for a full refund?

5) Is piCorePlayer compatible with Apple Computers?

6) It appears the 'Pi' portion is open to the elements. Is there a housing to keep dust out? Is it necessary?

7) How does this DAC differ from the DAC prototypes that Tommy sent me a couple years ago? [This should be directed to Tommy, I suppose.] I ask because I did not care for
    them. If it is materially the same, I will have no interest in your product. (Sorry, but honesty is best.)

I look forward to your response.

Regards,

Michael
