Difference between MS, MS Pro, and MS Magic Gate?

[Unregistered]

Hi, sorry for the newbie question, but I'm really confused about the difference between the 3 memory stick models. Can anyone explain it in plain English? Thanks very much in advance.

The Magic Gate white memory stick is only needed if you want to use Sony's proprietary ATRAC3 music format. Otherwise it does everything else.

The regular purple memory stick does everything too, except for the ATRAC3 music format, but does MP3's just fine.

The MS Pro came out and now offers higher capacity for the NX and NZ Clies. It does NOT allow ATRAC3 music! You must still install a MS Pro driver on the Clie for full functionality.
