Okay, I'm not saying that adding a feature to mask the password on the iPad would be a bad thing. In fact it probably would be beneficial, if enough people asked for it. You'd have to communicate that concern to Apple, however, and not a user forum. It would be useful as one person pointed out, while it is connected to a projector.
It's your claims that are quite interesting. I also use an iPad for some work related tasks; however, I do not utilize it to store anything sensative because that's not what an iPad was designed for. That's what my laptop with encryption is designed to do.
Here's a quote from your last post:
"I don't have a single password other than the one for my iphone lock screen that is less than 15 characters long and not randomly generated. Yet on my iphone it doesn't display and my password has been the same for 3 months (since i received it) while i must memorize a new password for my ipad every three days from friends and even total strangers figuering out my password."
If I'm correct in reading your post, you are in contact with friends and strangers on the order of at least every three days, who can figure out a 15 digit randomly generated password. If anyone can ever, without utilizing some type of social engineering, guess a 15 digit randomly generated password, then you must reside in a community of mathematical savants the likes of which the world has never seen. As I pointed out to a previous poster, the number of random possibilities in a group of only 6 digits is 1,000,000, so someone being able to figure out a 15 character randomly generated password, which I assume also contains alpha characters, is quite impossible. And really, who would go to all that trouble to gain access to your iPad? Sorry, I'm not buying it.
