The brilliant performance of a refurbished DELL Latitude reminded me of the seven wonders of the world and encouraged me to write a 7-fold review after an extensive 3-week use:-1. Battery backs up for more than 4 hours with Visual Studio Code, Google Collab, and a little less than 100 Chrome tabs working simultaneously.2. Dell Audio with the inbuilt Dolby Surround is enough to drool you in & out.3. Touchpad is buttery smooth.4. Touchscreen responds even at the pointy edges.5. The webcam quality can compete with your smartphone front cam any day.6. No heating issues; excellent ventilation.7. 128GB SSD is worth every penny. The system will boot up and shut down before you cook your Maggi.
