Good informaton. Thanks. Man, I just want 15"-ish laptops with good displays and keyboards that don't leave me off-center. I first used an Inspiron 6000i, and it was a fine machine for a decade or so despite being consumer-ish. I bought it new for a lot of money. I was young, but it never died. It still works. I replaced it with a used Dell Precision M4500, which was a whole different class of machine: It was spectacularly useful, and the one-screw magnesium bottom-plate was amazing. The display was astoundingly good. But the machine died: As near as I can trace, the IC on the mainboard that controls the backlight gave up. A replacement mainboard did not correct the issue, presumably because it also died for the same reason. The Precision M4600, the next newer model, has a numeric keypad, so I hate it. Same with other later Precision laptops. I'm a lot less critical about key-feel than I am about being centered on the screen. I often use my laptops as literal-laptops, and keeping my eyes and body centered seems useful to me in ways that numeric keypads on laptops cannot allow. I lust for a machine newer than my T530 that is also "serious" and that has a 15" display and that lacks a numeric keypad. : I grew up on an 88-key XT keyboard, wherein NumLock was still useful and it allowed me to choose between having arrow keys or having a numeric keypad. I thus learned to use top-row numbers because that allowed me to use both top-row numbers and arrow-keys at the same time, without actuating NumLock. I have not changed. (I do not wish to change. I do wish to keep my hands mostly-centered on the screen, though.)
