TFA states that it's a general problem with soft drinks, and the really serious cases involve patients that drink multiple liters every day. Not that there's any particular benefit to more reasonable consumption (say, 20 oz/day), even if it won't put you in the hospital.

Cheap and effective heatpipes showed up, and have been adopted by just about everything now. A good heatpipe is comparable to a basic water cooling setup, but it's a hell of a lot more reliable. They're sealed and have no moving parts, making them much better to stick in your laptop.

On the nerd/enthusiast side of things, I gave up my watercooling rig for just this reason. When I built a new computer, I just got an ordinary bigass heatsink, since it would give me 95% of the cooling for much less hassle and money.
