I am not talking about Linux for a particular use. I am thinking of the varied customers I have, each of them using their computers in different ways, and saying, "This won't work". Sure, it would be fine for some.
As for the command line, if you Google Linux problems you get command line answers. That's still a problem.
Yeah, that's totally true. Linux is a OS that allows you more control over the system (even if you are a Powershell advanced user, but is true it lacks of the advanced GUI Windows has (after all that was the propose of "Windows" and the first Apples at the beginning of the computer revolutions, the GUI) and Linux was a Kernel without the GNU GUI completely naked and was improving the GUI subject over the years (still needs more improvement).
That the the thing with private software, Windows has more developers in a payroll (with multiple zeros) and Linux Foundation doesn't has too much resources (and most of the devs are not Linux foundation related) so I love FOSS software but is quite difficult to reach the quality of private software (in the Operative System area). That's where companies like Red Hat (with its subscription model) and Canonical behind Ubuntu achieve better results in some aspects. They have more resources and visibility talking with the manufacturers and making more money through other means.
I still need a file explorer like windows has in other to see all my devices in a graphical way and with better control over my searchs or the menus with more options. Or a process explorer which gives me the control over my resources that process explorer does, but the distros are making great progress over the years

(BTW I am more a CLI guy, but i realize some times are quite more efficient or, at least practical, to use a GUI).
As for your English, that reminds me of a joke:
If you speak two languages you are bilingual. If you speak three languages you are trilingual. If you speak one language you are American.
As an American, I think your English is frigging amazing.
Hahaha Thanks for your compliment. I start with the english thing playing online games, so piked up a bit of the language by ear. I learn it the hard way over the years (probably 10 years), by ear which is the toughest part for an Hispanic guy, the listening (and without living in a country where english is spoken). So the easiest part for an Hispanic is the writing, but is the part where I make many mistakes (particularly, the grammar structure). Is much more difficult to you, native english people (uk/americans) to learn Spanish properly than to us learn your language. Our grammar is quite more complex and rich but your phonetics kill us.
Actually, IIRC the most of my friend list on my games were americans and the joke is true

, they spoke only American (most of them at least).
But this, usually, happen for a reason: Spanish is the 2º most spoken language in the world, but 80% of the most interesting documentation (especially Tech) is written in english (it's like the standard language; in terms of communicate knowledge internationally), so... the odds of finding someone who speaks multiple languages is higher if they are non english native parlant .
Your English is fine.
Jeez, I'm Australian and my English is terrible!
Haha I talk with some Aussie guys in the past, yeah is difficult to understand your accent. But to me the Scottish one is the toughest english accent I found.
BTW I love your country, incredible landscapes... but I am fucking afraid of move my ass there because when I see an insect (bees in particular) I run like the fucking bloody dam bitch I am. Period. So you can I imagine how "calm" I would be living in a place where bees are the tiniest source of my fears. To me would be like visiting Jurassic Park (the part where the animals are running free of their jails, into the fucking wild) hahaha.
And the hardest part is swearing in a foreign language. I'm reminded of a lovely phrase I read decades ago - I can't remember who wrote it but this has stuck with me:
Yes, in your case is difficult because you speak a different form of English, and you know the different between your words (the British and the americans ones). I speak mixed and the people don't care about that because they know it's not my first language, so i can make that kind of mistakes but to you is normal (is like to me try to not use Mexican, Argentinian or Colombian words). Thus, I love to swearing in english you can concatenate multiple swearing words so easily hehehe (for example in the paragraph before in this post, you can say f#cking this f#cking that and use bloody or similars in the same sentence, wonderful).
