It was a kinda cool design, while also being overwhelmingly lame and stupid. The droid socket had no room for the Astromech's legs, so he presumably had to take them off to get inside the ship. It also was way stabby on the back side, with the middle pointy part plugging into the wall for docking and somehow supporting all the weight of the ship.
The N-1 was most remembered for being used in the least exciting space battle ever witnessed. Yawn.
