Apparently the corruption that ensues relates to the interruption of wear-leveling activity on flash-based storage. More and more stuff uses flash memory, and as you note, when in laptops, this wasn't much of a concern because of the battery - enabling a graceful shutdown even if it ran down.
It's my experience that HDD are less affected by sudden power cuts, and Pi can now boot from USB HDD if desired. Most Pi people are going to SSD for speed gains, though. Ironically. It's a bit like turbocharging a Honda Fit.
