I just received my external DVD Burner LaCie and I'm very impressed and satisfied with this accessory. The external design of this burner is really good and it has the perfect size to be considered a companion for any UMPC.
It comes with Easy CD Creator, a USB Cable to power the device, a USB cable for data transmission, and a power adapter. I tested it with my Samsung Q1 and it works very well. And the best thing is that I paid for this burner 3 times less than what I would have to pay for the original Samsung Burner which is just a CD Burner/DVD Combo. This one was refurbished and I paid only 50 dollars including shipping. The new one can be bought here and the price is $129, 55% less than Samsung's.
