One obscure downside of having so many TLDs is that if you type something like "chrome.search" in the address bar and press Enter, it won't search for "chrome.search" in your default search engine. It will try to navigate to it (unsuccessfully), because ".search" is a TLD nowadays.
I do this all the time with the iPhone keyboard. Because the dot is only there for URLs it’s exactly where I normally hit the spacebar at (which expands to fill where the dot for URLs is). Drives me nuts. I can’t be the only one.
