I'm looking for a PDA, but I don't know which I should get...  I want a color screen for sure.  I also want a decent amout of memeory, but an expantion slot(particualary Compact Flash)  The MAIN features I want though is the abiliy to play decent sounding MP3s and Movies(off the expantion card.)  I know my dads will play short movies off the internal memories.  Am I looking for too much in a PDA?
