Hi there, I'm sure one of you knowledgeable people out there can tell me this. Are these two products basically the same, except for memory size? I have it that the DM3 has 4 Gig and the DM5 has 8 Gig. I can't see any other significant distinction between the specs for the two machines aside from this. Is that right or have I missed something. Thanks in advance for any help. It is genuinely appreciated. Best wishes, Mike Higgins, Email: m.j.higgins@xxxxxxxxxxxxxxxx Address: 1 Portland Court, Sheffield, S6 3EW, UK.
