My mate had a gorgeous new Samsung laptop. It was powerful, looked the part could be carried anywhere... as long as you didn't also have 2 weeks luggage to carry around.

He then went to USA for 2 weeks. He didn't want to take the laptop, so he bought a smaller net-book, just to check his emails, play music, and a bit of fun on the journey.

Would he have bought a Chrome-book if it had been out? Err yes. Why? Because that was EXACTLY what he wanted a pc to do.

It won't replace high end laptops, for now, think audio/video editing. But there is far more than a "niche" for it in society as a whole. in fact the niche, will be the high end computers!
