I typed them over or cut and paste from the imported txt files where possible.

People say that the contacts can be imported if you export them to csv, I tried several times and various ways but it has not worked for me.

The memo was the other big dissapointment. While Palm OS seems to have the memo in a database structure. I use Notes on the N810 and that uses a file system structure. So while on the TX I would open memo and immediately see the records/notes listed and can go to any note by clicking on it. On Notes I have to open Notes, then browse for the file within a folder that contains the note I am looking for.

Perhaps there is another application that does a better replacement for Memo but I don't know of it.
