Here is another stand-alone CD burner that should come in handy. Barring any copyright protection, the SKNET portable CD/DVD station should come in handy in backing up or making extra copies of your discs. All you have to do is insert the original disc, copy the contents to a buffer and then insert a writable CD and you are done!
SKNET comes from Japan and is expected to be released in the coming weeks. Hopefully it will also be available internationally.
