.MOBI ? Would city domains like SanDiego (.MOBI) (dot Mobi) be useful for SEO and in other ways?

I have an opportunity to take on some .MOBI domains, and am trying to decide whether to do it.


Do you think city domains like SanDiego (.MOBI)
(dot mobi... I'm separating the words, so that this doesn't get indexed into Google)
are useful for end users?


And does anyone know if keyword domains are still helpful for SEO purposes?

I don't mean for mobile sites, but just in general, are Keyword."TLD" (TLDs like .click / .site / .website / .online, etc) still very helpful for SEO?

And for .mobi in particular, does Google view it as a general domain extension, and not something specifically for mobile web sites?



I figure even if it isn't useful for SEO, it still is very easy to remember and has normal renewal fees.

I could see it being used for:

- A general site about the city
- Or something related to mobile phone services
- Or an online store selling phones
- Or many other things

And the renewal fee is only around $15/year.

In contrast, SanDiego."TLD" is a premium domain in domain extensions like:

.xyz = $219/year renewal fee
.page = $273/year renewal fee
.blog = $546/year renewal fee
.shop = $1092/year renewal fee
.auto = $2061/year renewal fee

...etc.


So do you think city domains like SanDiego (.mobi) would be worth $15/year?

And do you think end users / web developers would buy something like SanDiego (.mobi) for something in the hundreds? ($xxx)

Thanks
