thanks for the sharing of your usage.
that is probably the best I thought, but one issue annoyed me is it 
seems have problem to record the internal sound. what I mean is if you 
are enjoying a streamed song and chatting with someone online, it's hard 
to record those sound you received from the network -- your own sound or 
any "external" sound is well recorded, not sure you have the same issue 
or not?
