Corporations source them almost exclusively for their durability, performance, and lightweight. I've owned and used one and can speak from personal experience, not just reading reviews.
I have worked in the computer industry (hardware assembly & repair) for a couple years now and have had no real problems with the durability of ThinkPads (with the exception of the power cord - I have soldered many).
The thing is that all things come at a premium be it cost, duribility, or quality of software. I am sure that Apple with enough money could incoporate any feature ever fathomed - but at what cost. The weight may not be the big deal for 99.9% of consumers or Apple for that matter but what affects that same 99.9% and Apple is the cost of incorperating said niceties (production, R&D, exc all help to add cost to the consumer or cut into Apple's margins)
