I would think that you could also adjust the tracking system to better handle warped records, etc. And who knows - I sure don't - if it's possible to get a more accurate read of the grooves with a smaller reading mechanism. I'd have to expect that a low-power laser could be focused on a smaller spot than a stylus's contact area, for example.
On the other hand, I'nm surprised that there are 1000 of them out there. (Or are there 1000 of various designs, and this one now being advertised is new? It seems to be, since I don't think it's shipping until next month.)
