I wouldn't get the Acer Ferrari because of the slow harddrive, although I believe it can be easily replaced. The good thing about Acer, though, is that their computers come with a no dead pixel policy. So if there are ANY dead pixels, you can send the computer back.
I've heard that the Pentium M and the AMD 64-bits perform about the same in laptops (although I think I may have heard something about the 64-bits running a bit hot and the battery power might be a bit less).
So I guess it comes down to personal preference.
The paintjob on the Ferrari is nice...but then again, the CL56 can be bought at other resellers painted just the same, if you're into that.
Here is a review for the Acer Ferarri
