For machines that have only been in users' hands for 24 hours or so, the hits just keep on coming for the new unibody MacBooks. APC magazine has posted a "ten things you didn't know" review, covering some surprises and some well-we-thought-so's for the laptops.
Confirming our reporting from yesterday, APC spoke to an Apple representative in Australia who closed the door on any hope of Target Disk Mode availability via USB on the new MacBooks. Migration Assistant, which has been updated for these machines, will work over Ethernet or from a disk image of your source Mac, but not over TDM. The machines are running a new OS X build (figures); if you break the glass on the screen, you replace the whole screen (ouch!), swapping hard drives is much easier than on previous models (yay!) but if you lock your machine with a Kensington security cable, that will also block access to the bottom case (phew).
APC also notes a new internal feature on these laptops, and presumably on the MBPs as well, that MacMerc, HardMac and the Ars forums have pointed out: immersion sensors at various spots inside the case (previously seen on the iPhone). These adhesive dots change color when exposed to liquid, so the conversations at the Genius Bar where you insist "No, I'm sure that nothing was spilled on it!" just got quite a bit harder. AppleInsider has a diagram showing the locations of all eight sensors inside the machine, if you've got really really good aim with your spilled Dr. Pepper.
