Yes
I still have a few dotted around the house and garage, I find them much more comfortable/easier to use than the phone* due to tactile feed back (I know I've pressed the button, and the screen doesn't turn off after a few seconds) and it means I'm not changing windows on the computer and accidentally entering numbers in the wrong one.
*I'm also not worried about getting a £5 calculator covered in muck, or dropping it.
