I just switched from DirecTV satellite to DirecTV Now. This is a great article; however it overlooks a few points that are critical in making a totally informed decision.
First, the added hidden fees for the satellite-based service you don't find out about until the bill arrives. Want an HD DVR? Add $15-$20 per month. Second basic receiver, $7/mo. Regional sports fee, up to $5/month. "Texas (or whatever state you live in) cost revovery fee" $4.95/mo. I had a $72/month channel package that ended up really costing over $127 month. This was without any premium channels such as HBO or PPV. The bait rates offered to new subscribers fail to mention these fees and, after the first year of the 24 month mandatory contract, your cost will skyrocket to regular pricing.
Compare that to the Now service: $35 plus sales tax = about $38 per month - a savings of almost $90 per month. Since I signed up for the normally $60/month package during the first month, I got it for $35/month with a lifetime rate lock guarantee (what was AT&T thinking?)
Next, how much non-antenna programming per month do you watch. What is your ISP's monthly bandwidth limit before they gouge you with extra fees for more data use?
Comcast, as an example, imposes a monthly 1024GB data cap. If you exceed this for more than 2 months in any 12 month period, you'll be hit with added data fees of up to $200. As an alternative, you can pay an extra $50 per month in advance for unlimited monthly data.
I haven't figured out the exact amount yet, but it appears DirectTV Now consumes a few GB per hour using an Amazon Fire Stick. If you only watch 4-6 hours of DirecTV now per day and don't have other data hogs like remotely monitored security cameras or online gaming, you should be ok. If the total streaming is more than this, analyze how much data you are using now, how much DirecTV now you plan to watch and watch your cable bill carefully. If you go over in the first "grace period" month, prepare to shell out the extra $50 to Comcast each month for the unlimited data option.
If cutting the cord entirely and using DirecTV Now, you will need an antenna for local channels. If you live in the sticks, you may need a very powerful outdoor amplified one. On the plus side, over-the-air TV now offers a lot more viewing choices with sideband channels (2.1, 2.2, etc) that do not show up on DirecTV satellite.
You can't get extras such as PPV or NFL Sunday Ticket with DirecTV now. Not an issue in my case, but it could be in yours.
Finally, be aware DirecTV now is still a work in progress. There are times the picture will stutter or break up. In this case, you either have to sign out and sign back in or reboot your Fire Stick. It is getting better, but overall it won't be as close to perfect as the satellite option is.
I hope these tips help you in making your decision. Thanks for reading.
