As seen from the name of the shop, it's the place where we can find and buy (of course) the most advanced electronics there are. Electronics from all kinds of famous maker is here. And because I have a huge interest in movies, I would try to find the latest state of the art DVD recorder.
One other thing. If you have some pictures to print from your mobilephone or digital cameras, you can do it here also. But if you happen to be in Terminal 1, better go to "Digital Lifestyle by Boon & Co" at Departure/Transit Lounge West.
