“Talk to me, old friend,” he muttered, tapping the glove-friendly touchscreen with his thumb. The DS100E hummed, its fan spinning up despite the dust and grime caked into its bezels.

The rain hadn’t stopped for three days. It fell in steady, gray sheets across the industrial park, pooling in the potholes of the lot where Elias kept his mobile repair rig. Inside the van, the only light came from the sickly green glow of a check-engine light on a 2024 Audi and the harsh, backlit screen of the .

He reached for his high-end laptop, the sleek aluminum one with the 4K screen. It was his pride. But the moment he opened the lid, a fat droplet of water slid off his jacket sleeve and landed directly on the keyboard. The screen flickered, went black, then showed a sad folder icon with a question mark.

Twenty minutes of panic later—hair dryer, rice (useless), and silent screaming—he accepted reality. His laptop was dead. The Audi was blocking his bay. The customer was waiting in the customer lounge, scrolling through bad reviews of other mechanics.

Elias picked it up, wiped the coolant off with a rag, and pressed the hard-wired power button. No lag. No boot cycle. Instant-on. The battery icon showed 71%—it had been running diagnostics for six hours straight.

That night, Elias ordered a replacement battery for the dead laptop. But he also ordered a tempered glass screen protector for the Delphi. Not because it needed it. But because, after ten years of loyal service, the ugly brick had earned a little respect.
