AI Summary

Laptops have evolved from bulky, heavy devices with short battery life in the mid‑to‑late 2000s to today’s thin, lightweight models that match most tower PCs in performance and offer far longer runtimes. Because of these improvements, many users now treat a laptop as their primary computer, connecting it to an external monitor, keyboard and mouse. Some keep the laptop open to use its screen as a second display, while a larger group prefers operating with the lid closed. This shift reflects how modern laptops can serve both as portable and stationary workstations.
