its slightly thinner and weighs less by .2 pounds.
heat exhaust is in a worser place imho than the cl56
the silver color looks better imho than the cl56
it has more programmable buttons than the cl56 (which only has 2)
the keyboard looks cheap, its blue and seethrough (cl56 is solid black)
it doesnt have a kensington lock, the cl56 does
cl56 has room for a bluetooth upgrade via MDC (whatever the heck taht means!)
battery in this one is behind a panel which has screws, cl56 is swappable on the go by pulling a switch and it pops out
i donno these things are all very minor...
these two notebooks are very similar but theres less detailed reviews about it than the cl56... so u still dont know what the default core/clock would be with the 9700 card, its oc'ing potential, its thermaldesign and heat.. how hot does the hd get, does it warm up anywhere etc
