What about that dvd drive on the M2010? It looks pretty unique. I would like to have HD dvd or Blu-ray compatibity as well. I don't want to get somethign that I cannot replace the drive on. Whac, do you work at dell? If you do work there, , I would appreciate any info you can help me with. How about needing 2 gigs of ram? I had one gig in my last xps, and I never even got close to running low on memory. Would it make a big difference while gaming if you aren't using even one entire gig of ram? When do you use more than one gig (burning dvds?)? If I got a stock machine with one gig of ram running at 533mhz, would it slow down the processor? Do I need 667mhz ram when I upgrade to 2 gig to take full advantage of the processor's speed? I have read that you need 667mhz to use merom core processors, so if I buy a machine with less than 2 gig of ram I will do that, but I do not want a bottleneck if I buy a used machine with a gig of 533mhz ram to start with.
