Nice review and definitely answers some questions about the D620. I originally purchased a D620 then switched to a D820 when they delayed it for a month or more.
I'm really happy with my D820, but still thinking the D620 might be the best option if you are somewhat mobile. Although I spend most of my time tethered to a 24" Dell LCD at the office (via a port replicator), I still take my laptop out the door with me everyday and whenever I go out of town - soccer tournaments, vacations, etc.
I'm not saying the D820 is too large, it's just that when you are constantly taking it out of and putting it in a backpack case, the smaller the better. And when you have to carry it on your back, the lighter the better.
I got the WXGA+ (1680 X 1024) resolution with my D820 and I did notch the dpi up a bit - 96 dpi was just a little too small for my preference.
One thing that a lot of people don't realize is that whatever dpi setting you select is used whether you are using an external LCD or the laptop's. Since the Dell 24" LCD is 1920 X 1200, the 96 dpi setting is just too small to use comfortably all day, so I had to tweak it up a bit. Rather than switch it when untethered, I just leave it.
I do have a question for you. What do you think of the viewing angles? On the D820, I think the horizontal viewing angles are pretty good, but the vertical are very limited. Is this your experience with the D620?
I thought the battery life would be a little better. My D820 gets about 3.5 hours or better with the 6 cell battery with the LCD set to 1 notch below max, bluetooth and wireless both on. I did just order a 9 cell battery for a vacation later this month, so I'm hoping to get close to 4.5 hours with the 9 cell.
Again, great review and thanks for taking the time to share.
