I got my first windows laptop in 1999 (Toshiba satellite), and had 4 subsequent one’s since including HP Elitebooks and Dell Latitude Pros, and on none of them could I close the lid at a moment’s notice and start moving. I have had an Intel MacBook Air since 7 years ago, and I have never not been able to close the lid at a moment’s notice and stuff it in my backpack and get going.
