Hello all. I received my Dell Latitude D620 from work today. The system features specs very close to those of the MacBook (1.66 core duo, 2GB ram after upgrade, 80GB 7,200 RPM Hard Drive, 256MB nVidia Quatro graphics). The only thing noticably better is the graphics card specs wise. I had two macbooks before this and I was very rough on them for how noisy they were. Let me tell you what I think about this computer. Heat - it runs cooler than the macbooks but not by much. Noise - it has a constant whirl sound and when the fan kicks on (about every few mins) it gets really loud. The screen also makes a buzz when I move up and down in a web page. This seems like a screen inverter issue. Size - while not bad for a Dell, it is larger than a macbook. The weight is about the same. Screen - the screen isn't even close to as nice as the macbook. The color is not very accurate and it is not nearly as bright. Build / Feel - The unit is definitely a solidly built unit but does not have the nice feel that the macbook did. So, in review, while the macbooks may have the whine they are MUCH less noisy than this Dell. I think the Dell will be a fine computer but it has really made me realize the macbooks were better than I gave them credit for. I guess this core duo processor just makes laptops work overtime now days. EDIT: Recent developments Hard drive problems big time... loud and toasty haha! This computer exhibits the whine when on battery power much like the macbook only LOUDER! I just copied some images from one folder to another and the computer gave off a horrible high pitch sound while doing it.
