Although it is possible to do just about anything magically or mechanically, very little is purely one or the other. Many times magic can serve as a hedge to augment a technology.
For example, many found that magically rewinding a mainspring was easier than using a team of horses. It was more expensive, but several magnitudes of time faster.
Magic has also been used to create to solve problems with aether flyers. Although mechanically possible to seal a ship against the vacuum of outer space, it was usually easier to have a mage cast a spell to do so. (The also has the side benefit of making an aether flyer look like it is carved out of a single block of wood.) If a ship did not need to travel through a reagent vacuum, no one would notice. Magic is also used to create artificial gravity, and even as a means of propulsion.
Magic can also be used to augment weapons. For example, a magically augmented bow may have a greater pull, but the user doesn't feel the addition pull. It may feel like a 30lb pull, but actually be 50 lbs or more.
