Digital temperature sensors have some advantages (like nice factory calibration), but also so issues. The IIC/SPI ones need to be mounted to a PCB and also have quite a bit of thermal mass. They also need 4-6 wire cables. They are hard to attach directly to a point that you want to monitor.
The advantage of thermistors is that they are small, cheap, readily available with leads attached, and only require a two wire cable. You can easily tape them to whatever point you want to monitor.
The ADT7420 is $8 a pop + PCB + assembly + cable. Decent thermistors can be had for less than a buck.
