Every smartphone platform has a different way of doing it, but I actually prefer the way BlackBerry 10 handles minimizing and viewing recent apps. Just swipe up from the bottom of the display to see the last four apps you had open, and you can scroll down to view more. Plus, with Active Frames, you can see things like the latest weather and your next appointment. With iOS and Android you get static icons. I love Windows Phones’ Live Tiles, but you have to press and hold the back button to see your recent apps lined up vertically. Too much work.
