much bigger than 12.1 inches. My IBM thinkpad is 13 inches and my new Fujitsu P4 2.8GHz is 15 inches. I never heard of that brand but that is a smoking deal. I am using my old IBM thinkpad PII 366 for tuning because it is smaller and built like tank. My new one is for work and personal use. My new Fujitsu is too big and expensive to use for tuning inside the car. Congrats
