Yep, i said "files loaded into the memory", it's obvious the operating system in itself, the files that constitutes it, don't take 512MB of
storage, and won't requires 512MB of
ram to run. Some files
stored on the NAND will be loaded into the
ram, they will surely take a dozen of MB like i explained in my scenarios (stating numbers like "20MB"). All this matter is clear (OS files = surely XXMB in the ram, system features = maybe XXXMB in the ram, so system software layer/services = OS + features = XXMB + XXXMB = maybe XXXMB required in the ram pool) and you shouldn't focus on that (well, i know you wanted to talk about that to a few users since a moment but my post isn't the best suited for your explanation
).
But as you said, even if it's only 15mb of files loaded into the memory, how much more ram it will need to run voice chat, the DRC camera, all the online infrastructure, miiverse, notifications, the dashboard quickly accessible, suspended mode, and other functions ? This is the real question.
So your contribution would be more valuable concerning the SLC NAND. Do techies around think that Nintendo could manage to have 1GB of ram total, 950MB for games, 50MB for the "OS", with all the expected system features working while playing, the multi-tasking, the suspend mode, etc ? Could the dedicated flash be of any help for that ?
