While I appreciate that you added more information, I think the reason you did it was no different than mine, yet you act like I was trying to be something other than helpful. I corrected the other guy because HE was correcting someone else and getting it wrong. So I appreciate what you added, but that wasn't really my point.
I was using his number of 1500 when I should've been more precise and stated 1945 as you did. "Many" is certainly not "Most", that's why they're two different words.
For my subject, you seem to know a lot about the numbers of japanese and chinese kanji, but it seems you haven't actually written them with handwriting recognition.
I'll point out that kanji (as I assume you know) has parts of each kanji known as radicals. These are characters with their own meanings and recur often in various kanji. These are akin to "root woods" in english. For instance 食 (tabe), and other kanji that include it, have to do with food or eating. If you enter the simple radicals, a pop-up of all the kanji with those particular strokes will appear, making it in quite easy to enter even the most complex of kanji.

Of course I'm ASSUMING this is how they did it with the iPhone too.
It's really a great use of technology. I'm happy to see it applied this way. Now if they'd only make some 64GB or higher iPhones....
