I would like to launch into XBMC by default, then have a shortcut to open EmulationStation/Retroarch and a Web Browser and vice versa from each app. If the web browser is closed, then return to default (XBMC). Not sure what OS to to use, but I would like for it to be lean. I have seen a couple video's on youtube where a couple people have had similar idea's, but I did not see any images for download? None the less here are the links to give you a better idea.
The Ultimate Entertainment Raspberry Pi
I linked you to the part where he explains what he wants/how it works, but feel free to watch the whole thing if ya want.
The Ultimate Raspian
There is also a website (in spanish) here. http://www.ultimateraspbian.com/
I really don't need a full OS, such as rasbian. If I could get one of the other more streamlined XBMC OS's, such as Xbian/openelec to run the emulator's and a web browser, and have a friendly way of switching between everything I would be happy. In a kiosk sorta mode I guess? So my children, or anyone else would have no problems switching between the 3.
Any idea's? Maybe something out there I have failed to find? Thanks for taking the time to read, even if you can offer no help.
