It is for both business and home markets. it is thin and light with magnesium alloy chassis.
I have used IBM, HP, Dell, Sony, Toshiba, etc. IBM was good but ugly. Toshiba (business model) is bad. I won't touch it again. HP has a lot of its own stuff and IT people hate it. I am using Dell D820. It is fine but its software is no way close to old IBM. For example, you can dock/undock IBM anytime without doing anything. Dell, you have to use software switch before undock it. Otherwise, it will go crazy. Another thing is the switch between landired network and wireless.
But if I want to spend money on a notebook for myself now, I would go for SONY FZ. Buy it from SONY's business site so the machine won't have junkware.
