There was many a tear shed for the removal of MagSafe on the latest MacBooks and MacBook Pros. For good reason too! It was a great way to protect your Mac. The replacement, USB-C, has its own benefits too though.
The biggest being that it opens up the possibility for any other manufacturer to produce chargers for your MacBook. You can also pick up a battery pack to charge your laptop on the go. For anyone who travels, being able to use a large, hulking battery pack to power up your laptop is huge.
