That means iPad Pro 9.7 + Smart Keyboard is 667g, about 62% of lightest MacBook Air 11 inch(1.08kg), 413g lighter.
I considered about Apple's Smart Keyboard as the first option, I also got the chance to try my friend's Smart Keyboard, but at that time I felt it's a bit heavy. Maybe because I was using a iPad mini so when upgraded to iPad Pro 9.7, the tablet itself already felt heavier. I've looked for some 3rd party cases but a lot of them weight more than the Smart Keyboard(more than 230g). There are some "light-weight" 100g-ish cases but all feel not attractive...
So I ended up going back to Smart Keyboard. If it's almost the same weight, a portable and comfortable keyboard could help me in various ways I couldn't imagine(and it did!), the overall weight of the combination is 437g + 230g = 667g, almost half of MacBook Air 13-inch.
Note that there's no official data from Apple about the Smart Keyboard, I found it on some blogs, and some says it's 225g some says 230g.
2005. I was still in college. The phone I had was just a "pure" phone to call and text people, and even didn't have a camera.
2013. Now I have Macbook, iPhone, iPad, Kindle, all "rich" devices. With 3G network I can connect to Internet anytime anywhere. Life's been changed so much.
I never had a Samsung GALAXY phone, but after watched this video I was surprised by some of the new features. I've been using iPhone for 3 or 4 years, I'm so used to it and sometimes it makes me blind to see other innovations.
