I would hate to loose a method for determining whether or not the unit is locked. I agree that it is perhaps over kill to have an audible response from every key. Being able to drop the unit into a pocket or purse is one of the advantages over tape players and tapes. However explaining to everyone who asks "What is that beep" can be a real pain. On the other hand, finding that it has been unlocked, leaving the memo feature on, causes problems that require reconnecting to the computer, or at the extreme, finding your data lost, can be even worse. The problem with the memory key is something that I have gone into before. I have actually gone to the extreme of covering the bottom 6 keys. It helps the problem but is not a good solution. I wonder if there could be a sleeve made out of a hard substance that could be slipped over the unit for traveling. I have yet to find a pouch that will prevent accidental hitting of a key. Any hard containers that I have found are so bulky that they defeat the small size of the unit. Don't misunderstand, I still think that the Book Port is the greatest thing to come along since small tape players. I can't now imagine being without my Book Port. I also think that, in this day and age, it is quite remarkable to have a support team that considers the ideas of the users. Make it a great one Sharon
