Kmail, Thunderbird, Evolution. That’s pretty much it.

There’s always some weird niche client somewhere but it won’t be a hidden gem. Although I guess you can always use Pine (or rather Alpine nowadays) if you want to appear ubergeeky.

The nice part is you won’t have to go through all the bother of getting up and getting ready.

Look at the properties of the file in dolphin. It will show you various file signatures checksums.

Isn’t the problem that it’s blocked by a number of patents, or something like that?

Because when there’s a new hardware function, the driver has to add support for it.

I thought that version was generally well received?

Wasn’t there some water at one point? apart from that, fair summary.

A lot of things that were once creative experiences have been redone to death to the point that it can be difficult to understand what the whole hubbub was with the original.
So, yes, you have to think of it in the context of the era, which may require looking up what was made at the time, what had come before and what came after. It’s a bit like paintings or other pieces of art, some of them are interesting beyond what they just represent, but for what they introduced in the world as a statement when they were made (which, admittedly can sometimes be a bit obscure). There too, a little work on the public’s part is required to understand why one piece and not another is usually held in high regard (you’re then totally free to disagree, or not enjoy it, but context matters quite a bit).

Ooh, they have another one?

I read them both.

It’s a WIMP system. They all work the same way. Worst case you have to click around a bit.

[…] in reality they just know how it works

In my experience, they know how a few utilities and how a handful of programs work, but have no idea how Windows works. Not that many people actually know how Windows works.
Roughly figuring out the boot sequence of Linux is relatively easy once you’ve used it for a year or two. What happens when Windows boots? Who knows? kernel32 probably is involved at some point.

Linux/Unix is actually relatively simple and logical once you’ve figured it out. Windows is a messy dark maze with grues waiting at every corner to eat you.

Install Linux on…

Never mind, carry on.
