"Internet capable", "Internet ready" and "WiFi ready" are just marketing terms, defined by the marketing and ad agency the manufacturer uses.
Apart from reading the specs the best you can do is find your favourite TV-shop and ask the salesperson to show Netflix, Project Free TV and Hulu on the TV he recommends. But the etcetera might be difficult.
For example: if the specs they there is a "Netflix app", there probably isn't a "Hulu app". So the proof of the pudding is in the eating.
Hi, we have been educating ourselves on buying a new TV. We have read CNets info on Led,Lcd, Plasma etc as well as other websites to learn about all our options.. Can you clarify or point us to some good info or web links on the differences between internet capable, internet ready and wifi ready tvs? We would like a TV that would not require us to use our laptops or a Roku box to view Netflix, Project Free TV, Hulu etc. on it. Thanks so much for your help and any info you can give.
