Question 1. where can i get this product and get it ship directly to malaysia?

Question 2. i should work with a PDA. how do i connect it with a small usb end (connector to PDA) with a normal usb end (usb connector to PC)? and still get power into either of these devices?

 

1. You can find USB LCD touchscreens in about a gazilion sites Here are two
LinITX
CarTFT

2. What do you mean "work with a PDA" ? You mean get the PDA's screen on the LCD ? If so, it doesn't work that way. You need either a TV or VGA-out card, or a PDA which has either of these....
