I've got a 702... main reason was the problems I had with Sony portables....
(4 walkmans -tape... yuks-, 1 discman. All lived just a little bit longer
than a year...) The only portable that won't break and that is Sony is my
CMC-Z1+ portable GSM phone... (of which most consumer magazines write you
that the flip-down microphone will break very quickly...)

Got my 702 for two years now. No problems at all. Discs recorded on my MDS-S38
can be edited on my 702 and visa versa. Sharp has done it's marketing rigth.
They've integrated all electronics into one chip (that's what you call LSI) and
that cut's the cost. So the 7xx was cheaper than it's equivelent. Result: more
units where demanded than Sharp could deliver. Thus a production increase, less
quality control and Sharp found themself with a lot of units returned. Finaly
they got their stuff back together and the quality is good again. (This is MY
analysis of the UTOC problem after beening for more than two years on this
list! It's like the Malysian build 510 of Sony!)

I tossed them away after 1 day. I replaced them with the 888's of Sony.

Well, U=I*R. U can't change!! So if you increase R, you decrease I.
P=U*I, U doesn't change, but I get's smaller. Thus lower power consumption.
