Our family of four has been using a Roku 3 for a few weeks now and we've had no problem finding relevant content to watch. It's quite a traditional TV viewing experience, with of course the bonus of being able to pause and rewind. The latest version of the Roku interface is much improved over previous iterations and you can even download an app to use your Android or iOS device as a remote which can save time when typing in search queries. The Roku remote has a built-in headphone jack for late night viewing and in a nice touch, plugging in the headphones immediately mutes the sound on the TV.
Hulu and CBS All Access are the best places to start here, with Netflix as a potential add-on. You also may want to invest in an antenna to see if you can pick up a local channel that carries MeTV or a similar retro television service. Also, since the Philo live TV service has Nickelodeon and TV Land (and is super-cheap, starting at a bare-bones package for $16 a month), it might be worth subscribing to that as well.
If you're opting for streaming you have a lot more control about your choices. While a service like PlayStation Vue brings packages that are cable-like with more channels as they grow in price, Sling TV starts lower at $25, and offers more flexibility in what you can choose to add. If you only need a few channels, picking the right provider will be everything, and without contracts, you can swap services in and out as necessary. Pick up CBS All Access with its free introductory month to catch up on Star Trek, then jump over to HBO Now to binge Game of Thrones while you wait for the next season.
Pay-TV companies assume that if you want Internet only, you must be a cord cutter. To make up for you not paying for the TV service and associated equipment, they have begun capping data use at around 300 Gigs per month. If you stream video for three or four hours a day (average TV-watching time in most U.S. households), you will easily exceed this allowance. This means you will be charged overage fees, and to avoid those fees you will be forced into a higher-priced data tier. This is the most important reason to use a TV antenna - stream only what you need and use the antenna for the rest.
You can use a TV antenna to watch live TV, sure, but this isn't the 1970s. You need a DVR (digital video recorder). Consider the Tivo Bolt Vox (above), a system with six tuners and 75 hours of recording on a 500GB drive for $199.99, or get 150 hours for $299.99. Four of the tuners support OTA recording. (Don't get the high-end $499.99 version—that's cable-ready only.) The companion Vox Mini box sold separately lets you expand DVR coverage to other rooms. As the "vox" implies, you utilize voice control through the remote to run the DVR. Plus, it has plenty of built-in streaming apps. TiVo has a few other OTA DVRs, as do companies like Tablo and Channel Master.
The quality of your TV picture isn’t only dependent on the quality of your antenna. It also depends on where you live in relation to the signal towers. A quick and easy tool to figure out which channels are available to you is the Mohu Station Finder. It provides information on the stations available based on your address. It also provides an idea of the performance to expect from different antennas.
Another thing to consider is if you can set up antenna TV to catch local channels. While it might not work for everyone or everywhere, if there's a network TV show you just have to see live then this is the cheapest option. Digital TV antennas are easy to find with designs ready for home and apartments -- check out our guide for more info on how to choose the right one.
