[olpc-help] df -h command

[Anonymous]

When I do this command I get the following:

mtdo  1.0G    473M  552M    47%    /
tmpfs   35M    0          35M   0%     /dev/shm

I have installed, skype, Opera+Java.

Is this normal memory usage?

Should I clean up any un-used files?  How?
other than  rpm.bin files (which I did) 

My XO runs great and I do not plan on any more hacks.  My Uncle Bob always said, "if it's not broke don't fix it" 

I had the normal touchpad problem, but not touching the pad during booting has seemed to resolve that problem.  I have not had that problem in days.

Thanks for a great forum
