DM8000 is not yet even released in the market. there have been rumors that it would have been released Sept 2006, then December 2006, then October 2006. the month is past through half and no sign of any market launching, so most probable date would be early 2007 for DM8000. on the other hand, you should find it more appealing to look at other hardwares that DM is only beginning to promise. case in point: RSX and others http://www.engadget.com/2006/09/06/l...ebut-this-frid
now, as for specific stores in Dubai, you can wait for Abuhannah and other Dubai resident to answer that question.
