[Raak] Given that you use OSX and iOS devices I suggest you get the most basic TV that has the picture size and quality you like, and an Apple TV. In addition to having far more and better apps than a 'Smart TV', it will stream pretty much anything from your phone, iPad and Macs.

The trouble with Smart TVs is that they can be pretty poorly maintained when it comes to software updates; a year or two in and they're basically abandonware. The only thing I use mine for (app-wise) is Netflix, because all my servers and things are Linux-based and can't do DRM. And the Netflix app is terrible.

If my home setup were Apple centric (and I didn't develop this sort of thing for fun and profit), the Apple TV would be all I'd get.

[Dan] I've wondered from time to time what the Apple TV is. It looks like the way to go. That will bring to a total of 6 the number of Apple things-with-computers-inside I have.

Having made that endorsement I have to add that every individual option has limitations. Apple TV's is that they have a slightly more old-skool than average walled-garden approach, and their app selection is consequently limited. For example, because they have their own digital video store, they don't support any competing online video rentals like Amazon, for example. But if you want that there's a pretty easy workaround: install the Amazon Instant Video app on your iPad and then stream it to the Apple TV via Airplay.

The reason I recommend it is because you'll be able to access all your content from your various computers -- certainly anything that can be put in iTunes, and that includes movies you rip yourself with third party software like handbrake or source in other ways we won't go into -- and anything that it doesn't provide an app for you can fling at it from one of those devices. And it does have the characteristic Apple virtue that what it does have is less broken than everybody else.

[Dan] I've heard other people talk about Chromecast, and I have even less idea what this does than an Apple TV. Does it play nice with iDevices? Is it any good?and err indeed what does it do? The website is a bit vague

[rab] It's a web streamer you control with an Android device or (to some extent) a chromebook or the chrome browser. Essentially most things you can do on your Android device you can 'cast' to your TV. It's a bit like a dumber Apple TV, one that doesn't have its own onboard apps but just plays what some other device sends it (or tells it to play -- the distinction is blurred).

Depending on whether the app's media type and location is supported by Chromecast, the 'source' device may actually be doing the work of fetching and rendering the material and 'casting' the A/V output to Chromecast, but commonly it's just sending the URL and various tokens and chromecast is doing the actual fetching/decoding.

It's similar to having an Airplay-only device on your TV; bearing in mind that they are similar protocols but not the same nor interchangeable. Its main disadvantage is that it can't play content that's local to your network, so if you have your own movies and things you have to play them on your device and screencast it to chromecast. Which may or may not be well supported and look decent. For several good reasons I'd rather tell the TV-attached gizmo "play this file, which you can find over on that computer", than tie up some other device playing it and throwing the video to the TV. You can do the latter with Apple TV as well, but the thing is you don't have to, at least for any content that's supported by iTunes.
