Watching movie while going to work

Watching movie while commuting is such a great experience! I have a movie loaded on the Memory Stick Pro so that I can watch movie on my PDA (Sony Clie NX-70V). It made my commute time shorter than what it actually is. Sometimes I even feel like I want the commute time a bit longer so that I can finish the movie! If I keep watch movie a month or so, then maybe I can a much better excuse to get a hard disk based Portable Movie Player.
