The MMC card offers additional file storage (it shows up in applications and the File manager). Additionally, you can enable "extend virtual memory" which offers a sort of "swap space" which lets you run more applications at once (extending the 64mb built in ram with a slower flash-backed "hard drive"). Using a standard 770, you cannot increase the amount of space to _install_ applications: this is limited to 128. Booting from MMC (a rather complicated, advanced maneuver) lets you install as many applications as will fit on the MMC card you purchased - in this case, I believe the card will _not_ show up as "Removable Memory Card" in the file manager or applications, as it is essentially serving as the system's internal 'hard drive'-type device. -- Ryan Pavlik AbiWord Win32 Platform Maintainer, Art Lead: www.abisource.com AbiWord Community Outreach Project: www.cleardefinition.com/oss/abi/blog/ "Optimism is the father that leads to achievement." -- Helen Keller "The folder structure in a modern Linux distribution such as Ubuntu was largely inspired by the original UNIX foundations that were created by men with large beards and sensible jumpers." -- Jono Bacon, The Ubuntu Guide
