I feel the same about meditating near an powered-on electronic device, but in modern world it impossible to escape from EMW emitting devices. You can turn off all wireless capable devices in your home but can't control devices in neighbor house or nearby cell tower.
I have personally had more satisfaction meditating outside in fresh air near natural environment than indoor. I also know of many meditative experts who routinely visit remote areas in forests to practice deep concentration.
I would like someone to build an app to locate more favorable spot for meditation by calculating net wifi traffic in air.
