TSA Acting Administrator Huban A. Gowda specifically mentions laptops, tablets, e-readers and handheld game consoles as being subject to extra scrutiny. It's important to note that they don't specify size here; as phones get larger and tablets get smaller (not to mention laptops), it's unclear what devices the TSA considers "larger than a cell phone."

While this doesn't take effect immediately (the TSA notes that the program will be rolled out in coming weeks and months at domestic airports), you should plan on all electronics larger than a cell phone that are in your carry on bags being screened separately the next time you fly. It's important to note, though, that TSA Precheck passengers will be exempt from these extra security measures. If getting through airport security with minimal hassle is your top priority, then now's the time to shell out for this extra service.
