Because it is the most powerful handheld gaming device on the market with games comparable in scope to what wr see on modern consoles. With that in mind, you van play your handheld on the TV just as you would a console, even if compared to actual consoles it seems a bit lavking in power.
It truly is the best of both worlds and the potential is there for Nintendo to unify their handheld and console library on the Switch, making more games available for a single Nintendo device. Just remember, this is a handheld that can act as a console, not the other way around. It truly is a good gaming machine to have.
As for games, as of now Zelda is the only note worthy title. However many more games are in the works and other quality titles will soon be available. If this is your primary concern, wait until Mario Odyssey, Xenoblade 2, Splatoon 2, or even a few more great games to release you you give yourself options when you do get it. While I say the Switch is definitely good to have, timing is everything. All I needed was Zelda to get me started, but that is not the case for everyone. Get it when it feels right to get it, but it is certainly worth the money when you do get it.
