Woks... I think it really just depends on the person. Woks've got that use-me-to-cook-anything dynamic, and has the potential to replace pretty much... most of the other pots and pans you use. Like, these days, I tend to use a combination of my carbon steel wok (frying) and my stainless steel wok (steaming/braising) to cook pretty much everything.
But not enough ink has been spilled, I think, that that substitutability can also run in the opposite direction - if you already own and are comfortable cooking with (1) a large non-stick (or carbon steel) skillet and (2) a cast iron dutch oven, you can already cook pretty much anything that a wok can cook. Too many people view woks as 'the magical Asian tool to make the Asian thing', when really, it's just a nice, large, carbon steel cooking vessel with a convenient shape. Like, if you go around China, you can see plenty of homecooks whipping up meals with non-stick woks like this, which are really just slightly altered non-stick skillets by any other name.
So like pretty much all cooking equipment, I think that people should start off using what's cheap and convenient, then 'upgrade' only once you feel yourself getting dissatisfied with what you already own. Use a large non-stick skillet for your stir fries. If you find yourself stir frying a lot and getting kinda sick of wiping down your walls afterward, then buy a cheap non-stick wok from your local Asian supermarket. If you're finding that gets a lot of use, well then, maybe get a proper round bottomed wok together with a little gas Iwatani camper burner.
Not that I could see, but I might just be falling for a marketing gimmick. This is the one I bought
