Acer says its latest ultrabook, the Swift 7, offers “unprecedented portability.” The basis for this claim? A laptop that is 12mm thick at its widest point and under 10mm thick if you ignore the rubber feet. That is thin! How thin? It’s thinner than an Apple MacBook Air (18mm) and thinner than the Microsoft Surface Pro 4 (15mm with keyboard). At 10mm, it flirts with the thickness of many tablets, and is even thinner than some models on the market.
