And sata2 is better with a HD than a SSD?  All the comments I found said 
that Linux was seeing the drive as sata2, even though the chipset 
supported sata3.  No workarounds, and the posts were not that old.  Well 
we will see when the drive comes.

I have been having wierd behaviour here, like audio turning off. Can't 
tell if it is software (old and who knows what is running now) or 
hardware.  If f20 does not fix all the issues (USB sticks, but not 
drives, audio, external vga turning off then back on), it is time to get 
a new box.  But I am budget limited and x120e is at a nice price.  I 
will only get a 12" laptop with an eraserhead mouse button.
