My understanding was that the accelerometer was there to stop the drive in case of a fall. You wouldn't need that with an SSD, though perhaps if it still had an optical drive?

EDIT: I should add that both the HDD Macs I owned (a 2009 Macbook Pro and a 2004 or 03 Macbook) had accelerometers and I found a cool app for oldest that made a lightsaber noise. This was pre smartphones, so it was novel. My Late 2013 Macbook Pro does not seem to have one.
