Re: Most Linux distros are such flimsy OSes..
Erm, It's updated and maintained by enthusiasts, experts, and probably some purist nerds.
Its generally very good.
The downside is that their labours are to a greater extent voluntary, free, and generate differing approaches to certain problems (hence multiple distro's)
I certainly would not have the cheek to describe it as flimsy or outdated. Indeed look at your Microsoft windows installation change over the last 15 years, many of the folder structures have morphed into those used by Linux (or at least unix).
For my part, I want to buy a CPU - end of. I don't want to have to choose a Windows CPU, a Linux CPU, a Solaris CPU, or a Rasbian CPU, etc because each vendor has a beef with "secure" boot. This exceeds the idea of security and becomes, vendor specific boot, or pay me enough and you may boot (not great for a volunteer led platform) This is not security, its blatant commercial blackmail by nuking competition.
I use, and have used, many operating platforms, all have pro's and con's but I certainly don't want the anti-competitive full-stack model across the PC industry. It WILL NOT be good for advancing technology into the future.
