It might be the
names:
A C64 was a PC (sensu latu) and the latest Dell/Compaq octo-core gaming rig is a PC, so same-same. Name hasn't changed, so the massive technical advance is hidden.
The BBS networks were networks and the Internet is a network, so they're the same. Never mind the fact BBS networks were lucky to get email across the country in a few days whereas Internet users can chat real-time with full voice and video around the world.
Cell phones existed in 1985. Cell phones exist now. Guess which devices can access global databases in a fraction of a second and which devices were bags which had handsets wired to them so people could make and receive phone calls from their cars!! Again, though, the name remains the same.
People in 1985 had cheap cameras. People in 2015 have... cell phones.
People in 1985 had little black books with phone numbers in them. People in 2015 have... cell phones.
People in 1985 had really nifty digital watches. People in 2015 have... cell phones.
(Really, though, the fact cell phones have kept the same name is pretty amazing, given how radically the devices themselves have changed.)
