My other choice - reason for the outright enthusiasm for the PCG-U1 is that it is so durned small (2.5 times a CLIE PDA) and I want total portability, lifebook is still too heavy & I don't need CD rom (can plug into USB if needed).

I now use memorystick/SD cdard/CF card for data txfr between computers (PCG-U1 has memstick native, the others are thru PCMCIA cards that accept SD & CF). Also, I can either attach a CDROM thru the built-in network in PCG-U1, or I can copy CDROM to CF (have a 256mb one & can go to 512 & 1 GB CF cards now).

Lifebook is a very good unit but PCG-U1 has the near perfect combination of size, weight & features.

Cheers - Doug

PS my reason for keeping on top of all these devices is that my job as Principal Technical Architect requires that I know their capabilities - esp strengths & weaknesses)
