It should work but don't you think it's kind of limited?
You get one channel of instrument level input, no stereo, no mics etc.
I guess if that's all you need, ever, then fine.
I'm no whiz on micing electric guitars but I don't think guitar straight into recorder is the way the pros do it either, wouldn't matter much for keyboards.
How amusing that one of the features is that they include (Demo) versions of SONY software. Oh boy! As if people can't go download those themselves for free already. I also have to laugh at "Digital quality sound input". I've heard a lot of digital sound quality that is incredibly poor.
Anyway, it looks like a cool toy for someone playing about with their hobby. If it's cheap and satisfies that need then go for it. It doesn't do a whole lot for you though. I suppose if you have an outboard analog mixer and two available USB ports you could use these cables to bring left and right channels in from the mixer. Vegas and ACID could be told to assign to mono tracks to record from those two inputs. I doubt you'd be able to record stereo that way in SoundForge though.

True, but that way better than Sony giving away PP LE for free with their VAIOs.

I used to work for an embedded PC manufacturer and we did some bundle deals. In all the cases, we got the bundled software for free or close to it, but there was always the stipulation that all allocated copies must be distributed. For example, one of our bundles was a light version of a data analysis package that retailed for about $500 (in 20th Century dollars). We got them for $10 each, but we were required to include them in the next thousand SDK's that we sold with our hardware.
