I heard someone say Pocket PC, and yeah thats basically it, WindowsCE runs on pure ram.... and actualy saves on ram tooo...... of course the hardware is a bit different but im sure u can work something out...

but what im wondering is why do this on a PC??? Its pretty pointless, u can get a good HD and have everything on there, why risk speed and memory just to run it off of RAM???

I dunno thats just my opinion
