Programming works fine on linux, better even than Windows unless you're developing for Windows. Most gaming (other than some online games with uncooperative anti-cheat) is as easy as on Windows, where games are also likely to need a bit of tinkering. Web browsing is obviously fine, and that's most of what most people do (and so most people would be fine with "effectively a fancy tablet"). 3d modeling is fine. The foss equivalents to most Adobe software suck, but that's not really specific to linux.

Recently someone did the incredible work of getting Photoshop to run perfectly in Wine, but it looks like the original reddit post detailing it got removed for legal reasons (which is nonsense, it doesn't make piracy any easier). Adobe seems to actively work against any efforts to run their software on Linux.
