Random things this post made me appreciate:

Broadband - especially 1+Gbps connections (we are spoiled and I love it!)

Latency that can be measured in milliseconds per packet around the world, not seconds or minutes per character.

Multitasking not just locally, but across a network

Streaming video when I remember a 320x240 image taking FOREVER to download

Downloads that actually complete and don't corrupt most of the time.

Stateless connections that are easy to restart if something does go wrong

And so much more.
