Looking for recommendations for a good memo/note type app for a former Palm user. Have only had my ipod touch for a few weeks now and am looking to replace the functionality I loved of the Palm (last model was a Tungsten E). I have looked at reviews of several apps but am hesistant to invest in one only to find it sucks. Looking for a decent memo/note size (i.e not limited to like 250 characters each or some such), the ability to mark with categories (nesting might be nice), the ability to password protect memos (one by one, not the entire program). I tried searching this forum for ideas on this, and though several people have asked this question before, no one ever answers them. Surely there are former Palm users out there . . .
