Did I miss something??
1) 1MB flash ram: Any left over memory can be used as fast virtual hard drive space.
2) Built in clockport: You can use this for additional expansability, but it is recomended you keep available for when #3 comes out.
3) Flash RAM expansion modules up to 1GB are in development. With one of these hooked up to the expansion module you will have lots of fast virtual HD space.
It's Friday and I plan on installing one of these badboys this weekend for sure. I will share my experiences when I do.
