Hi all Sifu. Me totally newbie to this TV thing. Today is the 1st day i decided to buy a new LED unit for CNY.

Was browsing around and need some clarity:
1. Wifi direct - does it mean tht I can connect straight to my streamyx wifi to browse the internet?
2. Do smart TV come with build in antenna or we still need tht old TV antenna (still considering Astro)
3. For all smart TV owners, mind sharing with me your experience with ur units. How long has it lasted without any issues?

Thanks all ~
