I'm actually quite unhappy with this obsession with "thinner and lighter" mantra which throws away features at the expense of saving 0.01mm of thickness. These new computers don't have interfaces like Ethernet, DVD player, common interfaces for video. All of these is supposed to be outdated while it is very clearly not. You can't even do trivial upgrades like RAM let alone putting in new bigger SSD. These things are way too expensive to be entirely replaced just because you need 8GB of more RAM. When you travelling and wireless is painfully slow in places like hotels, wired Ethernet connection is truly a life saver. I hate to carry so many dongles and even worse, they are so easy to lose which can be devastating when traveling. I hate even more carryieng external DVD players because running Netflix is too choppy. When I'm presenting, I hate to carry dongles for VGA, DVI, HDMI etc to connect to projectors. Just few years ago, all of these were built-in to laptops and I used to carry zero dongles. Most people carry laptops in backpack which are often heavier and combined with the weight of all dongles it diminishes any weight reduction done on these devices. So these whole obsession looks pretty stupid to me and detrimental to getting work done for users.
