Planer. You don't need it, but they are useful.

Drum sander takes care of things over 12"
Not the best jointer out there, but used heavily, in tune and works for us. Used many times to create good gluing edges for the guitar project.
Dust collection unit and band saw. Ducts run along the top of the walls. This unit is good for our shop, but needs to have some of the ducts cleaned out on occasion. Especially if you use the planner with plywood or MDF type wood.
Bandsaw is modified with a riser block, other bits around the blade and a device to take the tension off the blade when not in use. . Great to resaw larger boards, cut raw veneer, big circles... Whatever... Gets a lot of use.
Lathe... This is on is a specialty item. Not great for turning bannisters or bats, but can swing a few hundred pound log around with ease. It runs off of 220/3 phase.. Try getting that in your home shop.
Shaper. Godd for cutting molding. Even better for holding magnetic lights and random tools for the lathe.

- It never gets used....
For cutting mortises... Used on occasion.
Some misc. hand power tools. Even hand belt sander in the mix.
EDIT: As mentioned by others... Everything is on wheels. Makes life so much easier when dealing with lager projects.
