A non-windows home computer/games system could be built again. The trick would be for someone like Acer to partner with Adobe and at the same time start building a good gaming SDK.
My son plays a lot of flash games. While a lot of the games are crap, there are actually a lot of them that are really quit good. When I say a lot, I mean A LOT. Basicly what would be need would be:
* Acer supply the Revo in a game system case. It is mostly there now.
* Adobe to add gamepad support to flash.
* Have the default setup so that a non-chatty Linux loads and boots into a full screen flash dashboard
* Write a decent dashboard in flash that can run the flash games and act as an 'app store'
With this approach, Acer could have their own game system ready for market with an extremely small team, tiny budget, and the system could be released at under $200.
Now, this approach could be massively improved from there with a little forethough. Things like, making sure that the system can boot from a USB port would greatly increase their market, as geeks could buy the system knowing that they could always repurpose it to a generic PC. For the general user, they would get a good gaming system, and for the enthusiast, they could boot into the simple game system, or plug in a usb drive and have a system they could run whatever they want on.
Anyone could write software for the system, and there would be a huge library from day 1. Since the initial environment being flash, would be 100% abstracted, they would not be locked into an x86 world, although they could stay there as long as they wanted.
They could follow up the initial release with added functionality like the ability to run C64 software, DOS software, Amiga software, etc...
The possibilities go on and on. The key is to keep everything abstracted. Heck, they could even go so far as to use a Wine, or ReactOS image running on a PC emulator to package up Windows games. By doing it that way, they don't tie themselves down to x86 and they don't care if future versions of the software have regression errors. They also don't have to care if ugly hacks are necessary to get the specific title to work, since the entire OS has been stripped down, and tweaked for the specific app.
