Lenovo is a subcompany of IBM, specialising in High Quality-laptops.
I use Lenovo and love them, the big advantage of them is they offer reasonable prices (though still more expensive than all the discounter laptops), but offer absolutely awesome quality. The laptop case is of high quality material, making it very sturdy. The cooling system is quite smart, making it not overheating like cheap laptops who crash all the time when running demanding software or if it's summer
. Also, they feature dozens of gimmicks as standard (Trackpoint in addition to touchpad, UMTS access, etc. etc.). also feature good suport.
Plus, they have a nice coolness deriving from their simple, yet effective design. Understatement for the win!
Can't say much about the current products of Lenovo, my laptop is some years old now, but still does the trick so I'm fine with it.
