Depends if you include individual hardware lines - remember Apple has been around for 20+ years longer than Google. If you include each individual product, Apple discontinued far more products before Google was even founded than are on the entire Google list (which is admittedly incomplete): https://en.wikipedia.org/wiki/Timeline_of_Apple_Inc._product...
Apple as discontinued a fair number of software products, just off the top of my head:
Aperture
Shake
Sherlock
iSync
ClarisWorks/AppleWorks (iWork seems to be a different beast)
HyperCard
WebObjects
iDVD
iChat (iMessage was never an AIM client)
