March 2001 was when I invested in a Polaroid 320 at £19 (in a sale). 320 x 240 (0.1mp resolution), internal memory, fixed focus, no flash, no zoom - the digital equivalent of a Box Brownie.
This was my first foray into digital while still using a Canon 1000FN (35mm). While it was still a few more years before I ditched 35mm, the potential of digital became quickly apparent.
May 2012 - Canon 600D - 18mp resolution, SLR and all the usual Canon EOS features.
