You can also order Dell machines with ME disabled. Additionally, most current Dell systems can disable Intel ME in the BIOS settings as well. This is a trap door setting - once disabled, there is no way to turn it back on.

From what I've heard, this disabling is done through the Intel HAM (high assurance mode), but I have no idea what the differences between the Dell and Purism approaches are.

(Embedded) System engineer, so lot's of hex typing and editing. It's a pain without full numpad.

How about a USB numberpad with all 16 hex characters? http://www.ipv6buddy.com/ I am in no way affiliated, I just searched "USB hex numberpad"

I've tried regular USB numpad, but it's just not the same as having everything in a single keyboard. You need table or stable base for that and typing is slower when you have to reach for it, especially if it's not fixed and moves constantly. Still better than nothing though.

I really want one of these, but the ergonomics look awful. Is there a technical reason they only come with low resolution (1080p) screens? (“Linux” is not a valid reason...) Also, as much as I would like a 15” screen, the off center keyboard is a deal-breaker. It’s just asking for RSI. Does anyone own one? How is the trackpad / keyboard / battery life / fan noise? Maybe I can deal with 1080p in exchange for a reasona…

> Also, as much as I would like a 15” screen, the off center keyboard is a deal-breaker. It’s just asking for RSI. Agree. Is entering numbers with a numpad so common use case that it justifies the inclusion of mini-numpad at the cost of off-centering the main keyboard?

Not exactly numbers, but unicode characters - yes. It's easier to memorize some codes if you have a numpad. Also it helps to have dedicated keys for basic arithmetic operations.

> numpads on a laptop are a terrible idea. I disagree completely. Having a numpad on a laptop is the only way of getting cursors and function keys (from Home to Insert to Delete) in a sane place. On my current laptop, were it not for a numpad, I'd have to press a Fn key every time I wanted to use Home/End. I'd also need to hunt for Delete somewhere above the Backspace, and PageUp/PageDown being on both sides of Up ar…

My HP laptop has a single column with delete/home/pgup/pgdn/end, like this: https://h30434.www3.hp.com/t5/image/serverpage/image-id/3646... This works very nicely for me.

That arrow key design is terrible though.

Apart from the fact that a lot of systems still have mediocre high-dpi support at best, there's also battery life, cost and the fact that 1080p on a 15" is more than adequate for most people.

1080p is considered low res! Crazy the times we live in. There are still laptop manufacturers making 1366x768 displays, the worst resolution ever invented. I understand pixel density is nice, but for the vast majority of workflows you do not need anything better than 1080p on a 15" display.

No you don’t need better than 1080p but most developers need crisp text and I would like to go further and 4k 15inch displays would be perfect for me as it would allow me to have smaller text without a loss of quality.

No you just want fancy things. Whatever, that's fine.

But it's not a requirement for 'most developers' - in fact the ones I know with high resolution laptops don't want them, they're just annoyed by lingering issues with UI scaling and tiny text. I can't think of a sane reason for having font sizes so small that you need 4k to display text properly. Text is plenty crisp at 1080.

Also this is a laptop. More pixels means shorter battery life.

Maybe what you really need is a desktop.

I've been looking at librem laptops, as I'd kinda like a dedicated linux laptop. But as with many of these kinds of projects, i18n concerns are secondary, and in this case, there is no scandinavian/nordic keyboard options :/ (And I do appreciate that it might not be quite simple to have all kinds of keyboard configurations available)

no french azerty ones either :(

That website cannot be real. The sarcasm is so thick you need a machete to cut through it.

It's surprisingly easy to switch to the English layout. As a programmer, it was refreshing to leave behind the convoluted key combinations while coding. (I'm looking at you, `tilde`, on a Hungarian keyboard) On Linux, writing accents using a compose key isn't much slower than typing the letters directly either.

Scandinavian languages do not really have accented letters, though. What we have in Swedish, Danish and Norwegian are three more letters than the English alphabet, with distinct sound and meaning, that happen to look a bit like accented A's and O's. These letters are very common in our languages and a without them would be nigh unusable; like a keyboard without V, P or B (these letters have similar frequency in Swedish)
