I used to, but I always hated having to practice. Now I wish I owned one so I could pick it up again.
I do play bass, but I may not be able to take all my gear with me when I move (particularly the 4x10 cab. That thing's a beast). The main difference between that and a piano is that, although a lot of songs do take practice to play, most songs have simple enough bass lines that I can just play a song and have it mostly figured out by the time it ends. It's much easier to play by ear, so there's no sheet music involved. In my experience, a lot of bassists don't even use tabs.
One thing bassists and pianists do tend to have in common is really short fingernails on both hands. A lot of guitarists only trim the nails on their left hand and use a pick for the right (which makes them easier to spot in public).
