Meh. hook an old computer to the TV... You'll never go back... Everything you can get through Roku or Amazon and so very much more. And you get the added advantage of super-configurable hardware and software with a full OS...
Mine is an old Vista era Acer that I paid 25 bucks for... added a USB wireless NIC and Wireless KB w/glidepad... less than 100 bucks in the whole operation... While I was going to sign up for Hulu, Netflix, and Amazon, I haven't, nor will I, as it's all out there for free, if you don't mind looking around... So no pay to play... no subscriptions, and the dough I am saving from dropping cable would buy me a very nice TV in a little over a year.
I had a small form factor PC connected to my TV as an HTPC. Problem was, it was too big for where I wanted it to be, getting it "out of the way" meant putting it in a cabinet and cutting off the airflow, or booting and powering off the PC anytime I used it or was done using it.
Going to Roku solved all those problems from me quite easily, and since it's attached to the bottom of my tv via double-faced tape, it solves the "out of the way" and darn near un-noticeable.
