I want to replace my DVD-ROM drive with a BenQ burner as insurance if my 1620 goes out. If I get a 1670 it'll mainly be used as a reader, I think. For $15, I figure I can't go wrong.
However, I would consider waiting for a drive that does quality scanning. Any guesses as to when Staples might offer a rebadged 1640, 1650, or 1655? I know it's just speculation, but what do you think?
