I've wondered for a while how fast we could make a phone (or PC) that operated entirely in RAM disk and used flash storage just as a one-to-one backup and storage when powered off. Obviously this would require your phone to have 128GB of RAM. You'd write changes to the flash storage, but it'd mirror RAM as closely as possible without destroying power management or storage life.
Imagine if there was no lag opening any app because everything was in memory. Imagine your code getting simpler because you don't need to load assets off disk - that's done all in one go at boot time. You want to render an image out? Just do it - a reference to a file is a reference to a file, no loading it or wondering if it's loaded.
Flash storage in phones is fast enough these days that it's probably not worth it, and simply giving traditional phones lots of RAM will probably give 80% of the improvement for 20% of the cost. But I've been curious about the idea for some time.

PuppyLinux did this for the Eee PC. Worked wonderfully. The only problem was that the distro eventually became outdated, filled with old packages.
The first Nexus phone had .5GB RAM and .5GB flash.
In other words, you don't need a ton of space. 8GB split among OS, apps, an running programs would do pretty well, honestly. 16GB is definitely enough. The question becomes more about how much space you want for photos and mp3s, and whether there is actually a benefit to putting those in RAM at all.
Then if the phone had originally 4 gigs of ram, you’d need an extra 4 gigs of ram for each app. I guess you could partition your ram to have 4 gigs as scratch, but that would limit the number of programs you can run.
RHEL7, and all it's derivatives (CentOS, Oracle Linux etc.) don't use tmpfs for /tmp by default, and they are arguably the most used linux distros in the world.
Hey all! My name's Neill. I'm your local linux enthusiast, web developer, cyclist, travel bug, and serial entrepreneur addicted to making cool stuff with awesome people.
I'm an experienced full-stack engineer and have been working with various companies and startups over the past four years and have taken on roles that include quality assurance engineering, frontend web development, mobile development, backend / database work, linux server administration.. if you have a vision I can own development from front to back and make it happen.
I'm always on the lookout for awesome workplaces with strong, engineering-driven culture to connect with and possibly be a part of and help grow. I learn very quickly and am always excited for whatever comes my way.

This is an idea that'll start gaining traction over the next few years. I was thinking of building something like this out in go backed by storj.io just the other day. We're also starting to see others like the aforementioned keybase filesystem, ipfs, maidsafe, etc.
