Lenovo(ThinkPad) is the best.And I'm using the R series now,it'll satisfied for you,trust me!

go for IBM or Lenovo best for business and best in looks! so stable and really a hardcore design to style on anyone!, anywhere

There are many brands available as far as the laptops are concerned.The competition in the market is so high that every one is giving the best in the market to sustain.Dell is the best brand and it is giving the best laptops.I think if you are looking for the better performance then Dell is the best for that.Dell is manufacturing the high processing speed laptops with the many latest features as well.So i would suggest you to buy the laptops manufactured by the Dell.

I would personally say that the Acer Aspire One looks pretty good for the money. Decent processor at 1.6ghz, and it can come with Linux preinstalled which means it will be fast, almost certainly cheaper, it looks good, and with Linux you don't have to worry about viruses, spyware, malware or any of the other problems Windows users have to worry about. And if it doesn't come with it preinstalled, download a copy of Open Office for all your office needs. It's free and works just like Microsoft Office. I recently bought a second hand IBM Thinkpad from eBay for my business and I am already wishing I spent a little more and went for the Aspire One. And this is a recommendation from someone who swore never to buy an Acer ever again after the problems I had with an earlier model.
