My 9 YO daughter expressed an interest in taping, so I gave her my DR-05 and SP-CMC-4u. She taped yesterday using my CA-9100 for one act, then hand held with internals for a song at a side stage. Then clamped to someone else and used the CA-14 cards with the PIP. I listened to all of the raw files a bit and they sound pretty good. She's gonna transfer and track. I'll post samples of each when that happens.
Bean, I think the stated battery life is 15-17 hours. That seems about right, though I haven't counted. And I have used it for playback quite a bit, too.
