That "3+ months" looks like FUD - with or without malice. But maybe it's because the original poster didn't cite the exact paragraph.

Jolla can't afford shipping SFOSXX in a hurry, especially if it comes with a price tag to download it and a bit of a hassle to install it. And even more because if this goes well, the door to native SFOS Sony-tier cellphones will be wide open. And AFAIK noone except Android and Winphone can get the interest of a top-tier OEM.

I also am very excited to have SFOS on a 5" device. Used to watch movies on the Jolla phone while long-distance commuting, a 7" tablet was too big, the Jolla phone seemed a bit smaller than needed (albeit a perfect screen, even if it was an exact quarter of the full HD). Funny, my everyday desktop monitor is 27" full HD, whereas Xperia X is 5" full HD. Maybe every cellphone manufacturer found that it's easier to add megapixels than making a phone battery last two days of heavy usage...

The only two reasons to upgrade from micro-USB 2.0 are data throughput and battery charging current.

The only time you really feel throughput between PC and cellphone is too low, it's when you want to run a full backup from scratch.

And high current charging is still debatable - especially when the battery is not replaceable and is not brand new.

Add in the insane diffusion of USB 2.0 plugs (the bike I'm going to buy sports an USB 2 charging port, not an USB-C), and maybe you will realize that 2017-2018 is still too early to jump on the "phone with USB-C" bandwaggon. It will take quite a while to see the USB-C replace the classic USB.
