In 2012, technology design went square, and I don't mean boring. Rather, the past year signaled a shift to sharp 90-degree angles as a design element. By itself, that change may not seem significant, but when you consider that so much in tech -- from hardware to software to Web design -- was built on the concept of rounded corners, you see that it is a notable design shift. Apple didn't follow the pack (Steve Jobs wasn't a fan of square corners), but plenty of its rivals did.
Microsoft was the biggest promoter of square corners, not only in the Metro interface of Windows 8, but also in the tiles of Windows Phone and in the physical design of the Nokia Lumia devices. And elsewhere, square corners dominated in the slight redesign of Google Drive, the Android Jelly Bean user interface, and many a slablike Android phone.
