I've been looking forward to that phone because their ethos seems to be in line with what I want: all the "directed" tools you want (phone, text, contacts, alarm, maps, Uber/Lyft, etc) but nothing that lets you get into "mindless scroll" mode like social network apps or a browser.
I recently got a Nokia 105 (2017) for my parents as the bespoke charger on their old phone broke, and it was cheaper to get a new phone. I played with it a bit, and as far as a phone goes it's top notch for making calls, but the lack of even basic apps like maps or messaging (other than SMS) make it pretty limited.
The phone has a grand total of 4MB of RAM in contrast with the latest smart phones which have up to 6GB. Android is too bloated as an OS for feature phones, but I'd love to see a new platform come out designed for limited RAM (maybe a few hundred megabytes) which it's easy to develop apps for, yet still produces devices that last for a week or two on a single charge. In developing countries these phones are still pretty popular, and from the comments people are posting here would go down pretty well with the HN croud.
I had a couple of what you could call a "smartphone" before "smartphone" existed (Sony Ericsson P900/P910), which anyway had a battery that normally lasted a couple days.
I have an (ageing) Samsung Note, but what I now use daily (since a few years) and carry with me at all times a Nokia 1280:

I can make and receive calls and SMS', it is tiny and extremely robust, it has been dropped countless times without any damage (shell and battery just "explode" and you have to find all the pieces and then reassemble it), battery lasts days, it simply fills most of my needs, without having to carry with me at all times a (bulky and fragile) smartphone.
Curious to hear what carrier you use it on. 2G options in the US at least are severely limited.
China will probably come out with similar clones before long... maybe even before the original:
