Having reserverd addresses based on MAC will guarantee that a specific device 
gets a specific IP address, *IF* the DHCP server is running, you have not 
replaced the NIC, the MAC is not being used more than once (Happy Meal cards) 
and a lot of other conditions are met (many of which, admittedly, do not 
apply to an HDHR).

Having a device set up with a static IP requires a lot fewer things to be 
running properly, and is generally simpler and less prone to problems. The 
most common problem is after a power failure, when you might not be sure of, 
or be able to control, the order in which things come up.

It can't be that hard to have the HDHR accept a static IP, but I suppose the 
target market is Mac and Windows users, which have no idea what an IP is.

It's not a major problem, just an annoyance for those of us who like as much 
control as possible over our networks.
