Nintendo Wii: Sold like gangbusters.
64bit Processors: The computing standard.
Battlestar Galactica: Considered one of the greatest sci-fi series of all time.
Facebook: Continues to be the world’s leading social media platform by literally BILLIONS of users.
High Definition: HD only got even more HD.
iPhone: Set the standard for mobile smartphone form factor and function to this day 16 years later.
Netbooks absolutely were overhyped, and the market for them died really quickly. They were barely usable, and by 2010 when tablets really started hitting the market, there wasn’t a space for them anymore.
I think the Netbook concept lives on in Chromebooks: Cheap, low power laptops that make sense in scenarios where higher cost laptops don't fit. Schools, kids, etc.
Some fraction of it was probably eaten by Raspberry Pi's as well. A 12V barrel plug was like the USB-C of 2008. For pennies, you got a intergrate anywhere Linux machine that could augment a lot of hackery.
