Not a serious backup option, but good potential for media server

As mentioned before, this product if far from perfect for backups, but if you need a small footprint device to store medias (divx, mp3s, ...) in your living room without the noise and bulkiness of most routers, this product fits the bill very well and AFAIK doesn't have any contender at all. Now the lack of uPnP is a big drawback, but one can hope that this might be added in the future through an Apple update or maybe something like FreeLink firmware...
