Most business oriented laptops generally lacks any dedicate graphics chip, but some have lower end chips. You will not see a GTX 780m in a business laptop, but you may see the GT 730m as an expensive option. For example, Lenovo's business oriented ThinkPad T440p and T540p has the GT 730m as a $130 option. I think in non-business laptops that option is generally between $50 - $80. At least in the case of the ThinkPad T series they are pretty rugged. Those laptops have been tested with be able to survive a 35MPH impact and can still be turned on so that the data from the hard drive can be salvaged. Most laptops would be utterly destroyed by such an impact.
Business laptops generally have a different tech support team that is generally better than the average consumer level tech support. Piss off a consumer and they might tell a few friends not to buy laptops from that company any more. Piss off a large company and you can risk the company cancelling a contract for 1,000's or 10,000's of potential laptop and desktop purchases in a single stroke.
"Home laptops" generally lacks a powerful GPU to play games.
