Funny, I've never had a problem "just pulling off the flash drive", although I've been exclusively using a linux OS for several years now.

The same problem happens with Windows -- but you may be missing what the problem is.
Writes are buffered, they don't happen immediately.

"Safely Eject", or umount, is nothing more than a way to tell the OS that you are about to remove the device, and to immediately flush the write cache, then detach the device from the OS.

...

Unless you pull the drive immediately after intense writing, you are most likely going to be all right.

...

Just want to point out again, that this has nothing to do with unix.
In fact, Windows will curse you with the dreaded dirty bit any time you remove a drive without ejecting, regardless of whether it was copying files something which unix emphatically doesn't do.
