I'm a newbie to Zorin, and Linux in general, having used Windows since version 3.1. I eagerly embraced every new version (along the NT line, which I jumped to with NT4), and loved using W7.
What made me want to switch away from Windows was the way MS imposed a mobile (i.e. touch-oriented) UI in post-W7 editions, even for mouse/keyboard users like me on my workstation.
What's worse is that - years after W8 - the UI is still an ugly, kludgy mix of touch-oriented (e.g. Settings) and mouse-oriented (e.g. Control Panel and all the more technical stuff).
I've got W10 on a Sony hybrid and I think it's a great mobile OS - way better than Android or ChromeOS. Microsoft did some genuinely innovative work in the mobile space. But on desktop machines? Noooo! We have 'File Save' and 'Print' dialogs that take up the entire screen, FFS! Look at the Settings app: all the UI elements are enormous (finger-sized). Compare those blue slider switches with the old radio buttons and check boxes. Observe the acres of white space. I honestly think my mouse mileage must have tripled between W7 and W10.
Microsoft should have done what Apple did and kept their desktop and mobile OSs separate. Then you'd get the best of both worlds.
I'm drawn to Linux (currently Zorin) because it's like W7: a coherent, mouse/keyboard-oriented UI. So much more elegant (in the design sense) than W10. Unfortunately every Linux I've tried - including Zorin - has left me disappointed or frustrated. Whoever claims that Linux won't freeze or crash are plain wrong; whoever complains about having to type in their password for Windows' UAC will find they must do the same, about as often, with Linux. Whoever claims Linux rarely needs rebooting after an update are, again, wrong. And is Linux really more secure? When it comes to security updates to patch new threats, Windows and Linux are very comparable; for several of the most recent years, Windows has required fewer.
I think for me the biggest challenge with Linux is how amateurish so much of the software seems. It's all too obvious that it is hobby-ware, developed by hyper-intelligent geeks who write fantastic code but who have no access to any usability labs, and who can't understand why their thrown-together UI isn't immediately obvious and intuitive to "normal" users. And despite claims to the contrary, that terminal window is never very far away.
So far, Zorin is my favourite distro, but I still find it frustrating and disappointing in small ways. Truth be told, I think I'd like MS to split Windows into mobile and desktop versions (the latter having a W7-like UI) and then I'd use that all the time.
