Lenovo laptops are the best ones. If I had enough funds at this moment I would rush out and buy today itself. Yups ...Buy Lenovo laptop.... Well that my choice.

Finally if you have a specific requirement that I need this or that then go for it, don't listen to anyone. Maybe taking a little extra time would be solving up your questions.

Linux or google ubuntu are good ones, very much less likely to be attacked by virus and spy.
