i dun see sony listing the x series in the catalogue anymore...so im guessing this series is gone...which is too bad bcos i really love this model!! the next best thing is the A series, which i hope the TS will bring in!

i think its probably the cost of producing X series is too high and if you look at sony- their MP3 product lines changes very face. almost every 6 months i see new models coming out!

in terms of comparisons...i dont think anyone has done that yet even though they have the same features but A series screen is smaller but dimensions wise, A series is slimmer than the X series.
