Sony sound quality is quite good. I have no idea what slide show thing ur talking about. Link?
Probably slide show is like when u viewing images can go seamlessly from one to another at certain timings. Dunno why you would want to view images on a music player anyway.
Sony music players dont support on the go playlist creation btw.
S754 and A755 have different capacity and color.
S545 and S755 are very different. Google images and u will know.
You can download manuals for sony players from their official site under "support"

For less than $300, I would say the latest E450 series is a good buy with the added SensMe and VPT.
S750 series has noise cancelling and longer battery life. I would not bother with the S540 series unless u need built-in speakers.
A840 series is now the top of the range but is quite bulky.
U need Sony Stage to create playlists iirc. Yeah u cant create them on the player.Thanx so much guys for the above posts! I have a better understanding.
Does this means that there is no playlist in the player at all or I must be connected to a computer to create a playlist in the player?
