It's not worth buying any of these 'Smart' TVs. I don't know whether it is a shoddy developer experience provided by the likes of Samsung / Vizeo etc or if it's the developers themselves (Hulu I'm looking at you) who do not maintain their apps which are constantly bug filled. I much prefer my old dumb TV that has a Roku plugged into it. Oh yeah, and I know it's not WATCHING ME.
Know what was state-of-the-art in embedded CPUs 10 years ago? The original iPhone. It had a 400 MHz single-core processor with 128MB RAM. Do you think app developers that have quad- and octo-core CPUs and literally 8 or 16 times the memory are going to optimize for the old platform, or build and maintain several versions of their applications?
Personally I'd rather spend of $35 ~ $200 every few years, instead of $800 ~ $2000, to have an up-to-date system.
