We didn't throw netbooks under the bus, Microsoft did
The first netbooks were a no-frills mini-notebook running Linux. They weren't great, but they were stable and reliable. With a huge amount of arm-twisting Microsoft were able to get the BestBuys of the world to only sell the Windows versions of the netbooks. As soon as the obligatory virus scanner was installed, the things ground to a halt. It was even worse when the Win7 Starter bloatware was forced onto the unsuspecting public. Add to that, the hardware specifications were very tightly controlled. If a reasonable screen resolution was to be had, then the full version of Win7 now Win8 had to be installed.
The tablet computers run an OS, which better suits lower performance devices. The truth is that people don't want Windows, but it was rammed down the PC user's throat. The result is that netbooks have become very unappealing. In fact, if the numbers are any indication, PCs have become unappealing.
Once again corporate greed and a whipped distribution channel have acted against the best interest of the computing public. Such behaviour is so common place that most people hardly pay attention.
