Adhoc poll: what's the most recent technology you've seen and gone "wow I gotta get that" and spent money to get access to, and were at least mostly happy with?

Not something pushed on you, not some new framework that was annoying to learn but everything is using it now, not some Next Big Thing that turned out to be a disappointment, or something constantly pushed on you by advertising that you didn't ever want to use, but a "wow that's neat, I need that!" technology?
