Wo_Ow.. that Panasonic FS-A1 WSX looks pretty c00l
hmm,

the sanyo wavy 70fd (2+)
The Hitachi MB-H50 looks very cool !
And in the "phone that looks like a computer" category, I like the ML-TS2. It's just too weird.
and of course my favourite, the Black/red Sony HB-F1XD.
Sony HB-501P! Like the 201, but with a built in Sony SDC-500 datarecorder! 
(And of course the Sony HB-F1XDJ, but that one was already mentioned...)
the Zemmix CPG-120 indeed is suuuuper, I've never seen that one before (in real life) what a stunning machine... I bet you could make any friend jalous by showing of your "upgraded and hi speed" MSX system Heck, it's even MSX2+ compatible!
