I've wanted to go over to Linux for a long time but I have no idea how to go about it. I hear about incompatibility problems with hardware and all the different options for different Linux OS's and that's it, I forget about it for a while to avoid the headache.
So where do I start? I don't even know how to choose hardware or what to look for. The number of options with Linux makes things a little confusing.
And although others here have answered the question before, I'm unsure what I have to do to stay 'safe' on Linux. Are there extra steps or is it just the standard, don't open dodgy links and turn off Java script in the PDF viewer kind of thing? Does Linux come with a trustworthy firewall/antivirus/malware detection? Is there a chance of Linux e.g. sending my passwords, etc, to someone or just letting someone into my harddrive? I hear that 'open source' means people can check the code but how do I know if someone has checked the code—I wouldn't know what to look for myself.
I followed the Linux subreddit but the users the can be rather… enthusiastic, which is great, but I need something far more basic to get started lol.
Is there a good step-by-step guide somewhere? Or can anyone give me some pointers/tips/advice?
I mainly browse, type, and read pdfs and other text files. No gaming, although I wouldn't be opposed to it. No need to be mobile; laptops are terrible for my back so I always use an external monitor, anyway, so I won't be using it 'on the go'.
Edit: Thanks for all the advice. I got a machine up and running from a bootable USB.
Any others who read the comments here because they're interested in trying out Linux – if you have Windows installed and want to keep it on your HDD/SSD, partition your drive within Windows. Then boot from the USB. You can partition your drive (and keep Windows) from the bootable USB but it's a bit more complicated and it makes it harder to create a swap partition and a storage partition. I had to go back and forth a few times to figure this out.
The situation regarding hardware support has improved massively in the last decade. The only components you may find don't work on a regular basis in a device are the WiFi, Bluetooth, and RGB controls (though these circumstances have also improved massively). I'd recommend installing it on an old computer instead of buying new hardware, as it will most likely work out of the box without you needlessly spending more money. Anything with more than 2GB of ram will likely run fine.
Security and Privacy
There is relatively little to due regarding security. It goes according to the standard don't open dodgy links and the like you previously stated. Furthermore, not only do you not need to install an anti-virus, I don't think any exist for desktop use. Most Linux distributions come with a decent built-in firewall. There is little to no chance of a Linux distribution sending passwords or other credentials anywhere, or granting access to your HDD contents. Most mainstream Linux distributions are regularly checked by various auditing teams, so that is of little concern.
Distributions
A distribution is mostly just the array of software installed around the base system. Some may be better suited to certain needs than others, though (almost) all may be modified to meet a given need. For those not familiar with Linux, I usually recommend Linux Mint for its Windows-like interface, abundance of pre-installed tools/applications, stability, and ease of use.
Applications
Browsing the web:
Firefox - Often installed by default, it is compatible with all major web standards (existing and planned.)
Chromium - The base for google chrome, for those unable to give it up.
Document Editing:
LibreOffice - Supports all major document formats, is preinstalled, and powerful in what it does. May mangle complex formatting on Microsoft Office documents.
Google Office - If your already in the ecosystem, it's one less thing to change.
