When I had the HTC One, I would do it sometimes. Mostly I'd do it if I already had my phone in my hand. However, the HTC remote software isn't very good in my opinion, and it was no where near a replacement for my Harmony 650 (which is a great universal remote fairly regularly available at $40 on sale). I have a Moto X and a Nexus 7 now, so no IR blasters for me. I do, however, use my Chromecast every single day, so I use my phone for that. To me, the phone/tablet is better for browsing and selecting content from large libraries such as Netflix, Hulu, or HBO, but a traditional remote is still superior for granular control like selecting an input, changing channels, etc. One place my phone really shines is as a controller for my Xbox 360 (via SmartGlass). Navigating an Xbox with a regular remote is clunky, and I don't like controlling video with a game controller, so the combo of Kinect voice commands and SmartGlass work excellently in that situation.
