Apple goes with USB instead of SD for MacBook Air Software Reinstall Drive

Apple is including an 8GB “Software Reinstall Drive” USB flash memory device with the new MacBook Air laptops introduced today.  I wish they had gone with SD instead, but since they can’t seem to justify the cost of including SD card slots in the low-end MacBooks this is the best alternative, and you can’t put a keychain/lanyard hole in an SD card.
