If you are using google chromebooks then you should be fully aware of the lack of support for basic applications with makeshift ways around such as RollApp being a alternative option than running the applications natively due to the locked down linux envirorment not allowing for native linux apps but rather only chrome web browser apps, so Python applications such as blender can either only be ran in a different linux environment via cruton,
RollApp works like this it is a service that cloud hosts VM's that have applications, you remote into those clouds for each window. Applications that are heavily used and or require resources are shoved into force requirement for paid for subscription. It didn't always be this way with approll but a rush of applications and money has lead to this. Their service isn't anything unique in any form or way there have been hundreds of options back in the day such as Joli OS which has been discontinued.
Really if you want a good service for linux based applications, remote VM's are the best option. But this means either depending on a online service of depending on simple old remote desktop google has to offer.
Either way you are remoting into a machine it is just how much control you have over it, It would be really nice if there was some way to run native linux apps but until google gets their heads out of their rear ends it won't be happening anytime soon. So Crouton away, developer mode must be enabled from the start else you will wipe the data from your PC but it will need a micro linux OS as 8gb of storage for most chromebooks. In other words remote in some windows PC and bite the bullet of LLLLLLLLAAAAAAAAGGGGGGGGGG.
FYI Drawing tablets, wireless headphones, most actually work with chromebook but again too locked down to actually productively use. Samething with game controllers but yeah not to many emulators options and not to many web games support controllers. FYI unity games do not work with chromebooks no matter how you try, really needs to be patched around or something seriously.
Construct 2 games barely work as most construct 2 games NOM NOM NOM resources. There are tricks to fix this, I will go over later.
As for RollApp their business model is just to make money, there is a promise of more apps and now even games coming to it, most of which are not really that good, but some are ok. 230 apps thus far, most of them simple 1 time use apps(junkware), and a few good ones being locked behind pay walls. Blender being the #1 I would use.
The typical ones like "Minecraft" being on the way, which only reminds me of the hunting ouya promises.
The current rate is $6.99 for their pro membership service needed to run many of the applications with the others setup as basically shareware.
The current free development tools are basically text editors like bluefish and notepad++ which basically only aid in programming, they don't compile anything. They are nice to have but yeah... they are just text editors with auto-formatting options.
Atleast gimp isn't hidden behind this paywall just yet. Hopefully they don't do this with it, keep in mind I understand they have to fund their services somehow, I just don't see a subscription base as ideal. I'm sure most of RollApps users are google chromebook users, but it is just remote services trying to make a buck off the lack of options for google chrome.
