Since 2004, the iMac was used chiefly as a game tool for my kids, as it was replaced by a Power Macintosh Quicksilver.

I recall that it had some malfunctions in the CD-ROM drive on the delivery, so I had to return it to the dealer. The present drive may, thus, not be of the same kind as when I bought the computer.

The Columbus was given away to my friend Henrik on August 20, 2007, who needed it for study purposes.
