I bought this product because the IBM / Lenovo ThinkPad notebooks are the most powerful

stable, durable and high quality I have purchased before... 
For example this machine (ThinkPad T60) is 5 years old and still works perfectly today, you only need to upgrade the RAM to install Windows 7, because this machine has good processor and video card ready to use with Windows Vista/7 Aero theme, and drivers can be downloaded from the website Lenovo.com 

Pros: 
Leak proof 
Roll-cage technology 
Hard/storage drive impact protection 
Military specifications testing for durability 
Software for Security (BIOS, Hard Drive, Boot, Windows, etc) 
Video Card ready for Windows 7 
WIFI 
Bluetooth (depending model) 
Fingerprint Reader 

Cons: 
Display 14" (don´t Landscape screen) 
Don´t have backlit keyboard 


Finally, I can say this machine can be compared in performance with some modern machines. (With RAM upgrade).
