Both the acoustic and electric are very different instruments. When you are first starting, here are the key differences:

1. Electric guitar strings are thinner, and easier to play. Acoustic guitar strings are much larger and a bit more difficult.
2. Electric guitar necks are smaller, and a little easier to wrap your hands around. Acoustics are a bit larger.
3. Electric guitar requires a little bit more gadgets to make it work (i.e cable, amp, etc.) Acoustic simply requires itself.

Those are honestly the pros and cons to both instruments in the beginning. Whatever one you start on will set the pace for your education on the instrument. The transition from acoustic to electric is much easier than vice versa. I tell most students to simply get what corresponds with their interests and what music they like. Both are very different instruments the further you get along.

Sounds like you have a great grasp on everything. Just remember they both are different instruments that have endless possibilities. Keep us posted along the way and best of luck.
