     Mine is 4239-CTO.  I'd like to try out SSD but I don't want to
give up a real HD or the CD/DVD drive.  I've considered the internal
SSD, but when I was buying my t520 it was not clear whether it was
bootable and/or fast enough to make putting the / partition on it
worthwhile. (Just did some quick googling and it looks like it is
indeed bootable.)

     For now I have optimus turned off in the BIOS and I'm using intel
only.  I'd love to have all that horsepower but I haven't had time to
devote to experimenting with bumblebee, etc.

     Interesting.  Do you have any clear indications of what made
the difference?
