The product idea was great, a <$50 device that gave you access to all the media you could want. Bonus there were apps and games.
However in practice its a deeply unreliable product thats deeply frustrating to use. It appears that not even amazon targets the stick for optimisation, as even the home screen is exceptionally slow.
Moreover it looses network connection frequently, but doesn't tell you. So you need to reboot the stick, but that takes an age because often there is some sort of memory leak causing the whole device to crawl.
Updates appear to be optimised to happen during use of your apps.
The virtual remote is deeply unreliable (and has been for years)
I didn't realise how bad it was until I tried a friend's apple TV. Much as it annoys me to admit, the apple TV, whilst twice the price (although its now more expensive) is 8 times the product.
