What kind of ruggedness are you looking for?http://www.panasonic.com/business/toughbook/semi-rugged-laptop-toughbook-52.asp
That's pretty much as rugged as you can get.
15.4" widescreen WUXGA LED 1920 x 1200
n Anti-reflective and anti-glare screen treatments
Intel® Core™ i5-2540M vPro™ Processor
– ATI Radeon™ HD6750M (512MB dedicated VRAM)4
– Intel® QM67 (max. 1915MB shared VRAM with 32-bit)4
Might be on the expensive side - but rugged notebooks do come with that "ruggedness" premium.
