Any reason keeping IDN-Domains like póker.tld?

Do domains like that have any SEO value or is it just nonsense?

In my opinion, it's just a big waste of time right now. I registered a couple IDN's in foreign languages as well as things like îphone.com, and i regret them all. I can't imagine why anyone would type îphone.com or póker.com into their browser.
