I've read that the Sony HS2 & HS10 have proprietary connections for PCs and that the cables are really expensive. Can anyone tell me if this is true? Is there anyone out there that has their PC hooked up to their Sony? Also, I rang my local Panasonic dealer today and asked when the AE-300 would be available. He said there was a trade launch this weekend but that the units would not probably be on sale until August! Is he talking from his behind?
