Without telling us what kind of things you want to do with your laptop, it's impossible to tell you "the best" one. Are you gaming, doing business presentations, surfing the Web, or just emailing? Do you intend to be away from a power outlet for extended periods, and need extra long battery life (and a swappable spare battery)? Do you need to store lots of data? Do you need swappable diskette, CD, and DVD drives? Do you intend to write CDs or DVDs? Do you need to connect to lots of peripherals (extra USB ports, serial port, parallel printer port, external display, keyboard, mouse, etc.)? Do you need the cheapest laptop on the market, or are features and/or reliability important?
These days, for some uses, a tablet may be better for you.
