yeah - I have the MP1550 too, but just wanted to see how an "all in one" solution worked out.

to be honest, I actually think a 2.5 external HD is "old news" anyway.
With 16 gb sdhc card + lurking for a 64 gb corsair flash voyager usb pen (which hopefully will be released soon) - space shouldn't be a problem


By the way, I use sanyo eneloop batteries. Only 2100mAh - but they don't lose power the same way normal nihm's do - so a week after a recharge they probably have more power left.
