nick - why does everybody like the microdrives..?
in my experence, recording to the medium with the pda setup, and using it to store movies ripped from dvd to my psp (with the extension pad), microdrives BLOW.
i think the specs are bullsh*t, but i dont know the technical details to explain why. what i do know, from firsthand experience, is that they eat WAY too much battery, and use more overhead - the processer buffer would f*ck up when recording 16/48 and fubar my recording, when ss cf cards held steady @ 2%, which is what my sd card setup does now, with a stronger, more powerful pda. and with video - the microdrive hiccups, when the same clips play flawlessly, with no dropped frames, using the ss CF cards i have...
from these experiences - i dont think i would ever use a microdrive for critical tasks, like recording, ever again. last time i bought one, the ss cards were a bit more $$, but the security/peace of mind (to me) is totally worth it...
not trying to slam the deal that you posted, just throwing my thoughts out there...
