I could live with using Linux for web browsing, but because it doesn't do the other stuff I like, I ended up just staying in Windows and eventually uninstalled Linux.
I'm still really rooting for the Year of the Linux Desktop, and it does continue to get better and better, but I'll keep rooting from the sidelines.
Second, Linux needs a standardised *and enforced* application installation method like .exe. One should never, ever, for any reason, ever, need to use the CLI to install an application. Yet there are so many applications out there which require the use of guides/manuals and the CLI to install, configure, or use. This is partly a dev preference, partly to save time, and partly because it's difficult to build and maintain distinct UI for different distros which each have their own quirks. People often ask, "why don't they release this on Linux?" But that's not actually what they're asking. They're really asking, "why don't they release this software on 20 distinct operating systems?" Each distro might have 0.1% of their total addressable market. Unfortunately, even if SteamOS enforces some kind of package manager like flatpak, that's not going to force devs to use it. It would need to be Linux-wide, and that will never happen. So we're left with fragmented install methods across multiple package managers, and a huge headache for people who just want their OS to get out of the way.
I really wish more people would mention the option of dual booting. Use another separate SSD to install your linux OS and that way you always have the option of going back to your Windows install. You can even reserve some programs for Windows and do everything else with linux.
There's really no need to approach it with a "screw it" attitude. You'll probably get yourself in too deep with that approach.
