Trait: Dislikes Gunpowder

[Sheogorath]

Some good points, but it should be pointed out that:
A) Flintlocks were developed and used throughout most of Europe in the 1600's
and
B) Bayonets may have been 'invented' in 13th century China :P
But they were in widespread use in 17th century Europe. I believe the French were the first to actually issue them on a standardized basis.
Of course, they were the plug-type that CA has gone on about quite a bit, and as such, would make it impossible to fire while in place. Unless you wanted to, first, launch a very large, very inaccurate, very short ranged, projectile at somebody and, second, cause your musket to explode :P

I think you might also be off on the reloading time. Its my understanding that earlier muskets could be fired faster because they usually featured a flared muzzle. That reduced muzzle velocity (and thus accuracy, range, etc.), but allowed for easier reloading. I'm not sure when that type fell out of use, though...

EDIT:
Curses! Lars beat me to it.

However, it should be pointed out, there were several 'non-standard' cannon types around. The Russians used Unicorns/Licorns, which were a sort of mixed howtizer/cannon and could (so I understand) be used in both roles. The Ottomans had a godawful mess of an arsenal which included cannons from the days of the Eastern Roman Empire.
Rather amusingly, several guns apparently commissioned for the Siege of Constantinople (which were later mounted in the batteries guarding the Bosporus/Hellespont) were used in the Napoleonic Wars, and apparently were sufficiently scary that the British and Russians only tried to take the straits once. Considering they had a bore of about 30 inches or something, I'd be pretty scared too :P
