Unless it has changed for a while the TSApre lines don't make you take off shoes and belts vs the regular lines. I also think they stopped making TSApre tahe laptops and iPads out of bags. But it may also have to do with equipment upgrade cycles and what was deployed to which lines.

TSA precheck was originally for avoiding removing shoes, belts, and laptops. I had it at some point and gave up because random lines kept making me remove stuff anyway, but only telling me that after my bag was already taken aside for search, so it wasn't worth.

Newer xray machines don't require anyone to remove laptops. It's about 50/50 whether I get a new machine lately. Just today at SFO, had to remove laptop but not shoes.
