You can think as much as you want. I didn't say they aren't competitors, I denied that they are DIRECT competitors as you claimed. Smartphones and tablets play games but they also aren't direct competitors to consoles. Even Wii wasn't direct competitor to PS360. Because the presence or absence of this competitor didn't effectively affect the others in the market. Switch is an indirect competitor or a replaceable for these machines. As in they compete for playtime or shelf-space on the store, and if neither Sony or MS keeps a viable plan on the market then consumers will go to Switch.
But on regular day basis almost no one changes their intention to buy PS4 or X1 because of Switch. Evidence is PS4 breaking record when Switch launched instead of sales drop.
Thank to say I'm malicious and probably evil with PS4 selling more than Switch in 2017 and 2018, so I have no idea where your point comes from. Stating facts that doesn't align with your beliefs isn't being malicious.
You see, they are direct competitors. The primary offering here is playing games. Tablets are for browsing and multitasking and phone are also for browsing, but primarily for communicating. Not gaming. The Wii did actually compete with the PS3 and the 360. The only difference in this case was that the Wii was marketed towards a more casual audience, HOWEVER, Sony and Xbox proved to competing for that same market later anyway, with things like the PS Move and Kinect. You and that other guy purposefully argue that the somehow the Switch isn't a competitor, in order to dowplay its success. It's really that transparent.
