Actually the H2 can modified to record 4 tracks; I saw a video on youtube.
By the way, if it can record 4 sources coming from its own 4 mikes, why the hell can't we hack to make the 4 sources coming from external mikes? I'm sure it can be done..
Too bad that every recording I listened made with the H2 sound a bit 'digitallish' and.. I mean, one from the R09HR is a lot of times better, in my opinion.
