My overall sentiments, more or less:
1990->2000 we went from very few people owning personal computers to wider adoption of PCs and broadband was gaining traction (I personally had @Home cable internet in 1998).
2000->2010 mass adoption of cell phones, starting with the flip phones to pocket PCs to the first iPhone in 2007. Social media (MySpace, The Facebook). Peer to peer networking, piracy (The Pirate Bay). Laptops. The first tablets.
2010->2020 mild improvements on the stuff from the previous two decades
EDIT: I'll give the last decade Uber (although I've only used it once) and AirBnb since that was a huge shift as well, but my overall feeling remains the same.
