For business use NEC and Panasonic machines are actually built better than MB/MBP's. IBM machines were also built very well - not sure about Lenovo but those 3 makers trounce Apple for build quality and the amount of physical stress a machine can take with Panasonic putting shock mounted SSD/HDD, spill proof keyboards, machines which can take 100kg/150kg of weight, drop heights of desk height etc and are lighter than MB/MBPs. The cost however is high, a light (under 900g) NEC i7 ultra-portable costs $3,000 but high end business users will go with such reliable and light machines. The software however is the weak end - and they still run Windows but if Apple licensed OSX to Panasonic people would not buy Apple hardware anymore.
