I have a 512mb CF card for my M3. Compared to my previous flash cart which was 256MB and only held something like at the most 2 decent GBA games, it's like a massive storage. At the end of the day, it's all about file management. Got a game you don't like? Why keep it on any longer? You can also back-up the save for future use if you must. I'm not too keen on using a huge chunk of the space for the multimedia side of it (like videos and MP3) mainly because I think the PSP excels in that area but at least it's a nice bonus. Seriosuly though, can you really see your self playing all 10 games at once? I'm still on the first Summon Nights game.
