While the iPad may have been a nail in the coffin, the death of netbooks has been obviously on the horizon since MS changed its tune and began to "support" them (MS support == embrace, extend, and extinguish). When the first EEEPC came out, it was a cool device: SSD storage, lightweight, better than average (for laptops) battery life, and it could fit in a fashionable woman's purse. These devices were extremely useful for science, diagnostic testing, playing, reading, etcetera -- in fact, these were the first real instance of mobile computing. Laptops were bulky, expensive, ran hot, and had terrible batteries. The first year of netbooks was somewhat of a golden age.
Enter M$. Now, what do netbooks look like? I checked last week, and it is now impossible to buy a netbook without a spinning platter hard drive. Linux netbooks are almost completely unavailable. I checked Amazon and Newegg. Both listed Linux netbooks that were "no longer available". The available netbooks are no longer much lighter or more convenient than traditonal laptops. In fact, battery life is about the only selling point they have left.
I figure it was just a matter of time before the public came to realize that netbooks are just about the same as laptops now, so they have to go somewhere else to search for convenient mobile devices. The fact that so many people are rushing to the iPad is just more proof that Steve Jobs -- bastard that he is -- is a genius at predicting the right time and climate to release a product. Just as people are fed up with MS ruining the very concept of the netbook, we have the iPad: long battery life, nice screen, hardware accelerated video, light and portable, all the things that MS has taken away from the netbook.
While anyone who buys Apple products is still a jerk, I think MS owes the hardware manufacturers and the public an apology for destroying a lucrative sector of the market and a useful product for people to use. Unfortunately, running to Apple is not an unreasonable choice. This just proves the harm that comes from monopolies being allowed to exist.
