===How much memory/disk is built in?===

The XO-1 laptop has 256MB of dynamic RAM memory, as well as 1024MB (1GB) of flash memory.  

Note: The flash memory acts as the hard disk.  Original specifications are outlined [http://laptop.org/laptop/hardware/specs.shtml here].

===How should I use the SD card slot?===

The [http://wiki.laptop.org/go/SD SD card slot] is hidden on the edge of the unit under the power button.  It is not intended for casual use, but intended for (semi)permanent augmentation of flash storage on the system.  To try to keep water and dust out of the main unit, it has a rubber seal that makes it difficult to extract the SD card.

As a result, we recommend using the USB ports for casual transient storage expansion or moving files from computer to computer.

You can install the XO software on an SD card to provide much more space for files and programs.  This is much easier with the F11 release than with earlier one.  Here is a journal of how one user did so: http://wiki.laptop.org/go/User:SDGathman#Running_XO-1_from_an_SDHC_Card

===How do I backup my XO?===
