If you don't disable quick-charge in the BIOS/UEFI many Dell Latitude batteries get eaten up in a matter of months, especially the 9-cells. I learned the hard way. When I bought the E6420 I disabled. Original 9-cell is still good after all this time. The 1600x900 is sufficient too, I don't know how people work off of 1366x768. Cheap $10 DVD replacement tray for a second drive. Great battery life.

You can still get them refurbished from Dell, sometimes with 40-50% discounts for $250-300. Very worthwhile for a second portable.

Absolutely no issues in Debian even with the dedicated nVidia. Even the keyboard backlight works with no issues.
