1. Netbooks are losing sales because the market is slowly getting filled.
2. Give me a netbook with good battery life, a decent i7 CPU, a video chip that can play modern video games at 1680x1050 resolution, AND a good looking docking station, then I will get one. 
1. Finally, a glimpse of smartness in this thread. Netbooks sales are slowing down due to the simple fact that everyone who needed one, just bought it. The others are buying used ones from people that thought they were buying a real notebook, instead of a high-specified low-power, low-performance product.
2. That wouldn't be a netbook.
I simply can't understand why someone still compare netbooks to regular computers or even to iPhones. They are different objects and they must do different duties. There's no need to buy a pricey hi-end laptop to send an email or to browse the web, so for these simple tasks a netbook is OK. But there is also absolutely no motivation to buy a netbook if you want to run Premiere, Photoshop, inDesign, Autocad or whatever hi-performance application. The only operating system that really fits well on that platform is - incredible, eh? - AROS.
