dogma's point about the Play Store apps is right though. ChromeOS was designed to keep everything in the cloud, but Android apps are different-- while currently running on storage-constrained tablets and phones, the Play Store on a laptop will feel a lot more like the App store on a Mac-- games especially will have tons of giant assets that will ideally be stored locally. But if you only have 32GB for a 500GB game... there's a problem.
When a device has a keyboard and 12" screen, it'll feel like a laptop and you'll expect a laptop-like installation experience, not a phone-like experience. That means not waiting a half hour for your game media to download every time you want to play a level...
Even a phone/tablet like experience.
The "AAA" mobile titles and the older PC ports take a lot of space, Xcom takes like 4GB, Shadow Run takes 2-3 GB, GTA takes like 2-3 GB also...
Even on my Motorola Droid the first "AAA" 3D mobile games would download 1-2GB of assets.
A movie from Netflix / Google Play can be 4-6 GB also since it's 2-3GB per hour.
If you have a Marshmallow device today with an SD card you can lock the SD card to that device, format it in EXT4 and encrypt it and then never really remove it and apps can be installed on it (usually), if you still running an older version of Android you have to root the device and pray that the app doesn't do root detection format the SDcard in EXT4 and mount it in /DATA (?) and even then you might have issues since the SD card reader on many devices can be quite slow.
If Samsung wants to sell 500$ devices with 32GB it's their choice, but why not offer models with more storage? Why all the chinese phones can come with 64GB as a base for 300-400$ but Apple and Samsung still offer 32GB for flagship devices that cost twice as much?
And more importantly why are people OK with it? seriously "X is more than enough" when in fact it isn't is not an excuse, the fact that you can get by with 32GB doesn't mean you should, your use cases fit your storage
capability not the otherway around.
When I bought the 128GB 6s I thought I would never fill it, within a couple of weeks I only had 30 GB left on the device.
