I was so excited when I saw the 2488 come out, but when I really looked into it I was bummed. To me, it's basically a 12 track unit. I don't like the fact that there are 12 tracks out of 24 that you are forced to pan hard left and right. To me, that's like losing control over 12 tracks.
I bought a Korg 1600mkII instead. It is one incredible machine. 16 true tracks and very intuitive to use. (by the time I was laying tracks, a friend/software developer with the Yamaha unit was still trying to figure out how to route a signal). It has a CD burner in it and is capable of red book quality CD's. There are some great mastering effects included and a multi-band compressor (although only 3 band).
Come over to my side! I don't think you will be disappointed.
