Can make reconfiguration a pain.
It won't cause disconnects.
Nope, in a small home network there's no real need to use DHCP at all, in fact, its just more convenient. Mark McIntyre
Depends, I have a couple of devices which offer no manual configuration whatsoever. They can only get an address via DHCP.

Setting a near-infinite time will mean that you risk consuming all available addresses at some point in the future. Unlikely for most SoHo users, but you did ask "Any reason...".
Does not compute - what are you referring to? With a well-behaved client and DHCP server, the lease renewal process should not cause disruption to an existing connection.
The overhead of lease renewals is very low. I suggest you set a fairly long, non-infinite, lease time (say 7 days?) and stop worrying :-)
Thats pretty unusual for network devices. What are they? I've never come across any network device that didn;t allow a fixed IP to be entered, so it would be interesting to know. Mark McIntyre
Long DHCP leases will do nothing for disconnect problems.
Generally a bad idea. I have problems with long DHCP lease times with hot spots. There are just too many wireless clients drifting around that automagically associate with anything. They fill up the DHPC leases and ARP table eventually causing a router crash or hang. For open hot spots, I go for very short lease times. Of course, if you have encryption enabled, this is not a problem.
Long lease times can also be replaced by "static DHCP". Lots of routers have this feature. That's where you configure a specific MAC address to always have the same IP address. That's handy when you wanna do incoming port redirection but don't wanna setup a static IP address on a laptop. The laptop may need to wander over to a different system and the static IP's will need to be removed.
The usual culprit is something basic like a printer server that lacks any sort of interface.
Hauppauge MVP Media Extender. It's a bit frustrating to be honest! I won't go into details but one of mine is at such a position in the network that if it changes address, I have to go and reconfigure a security gateway.
I guess Hauppauge figure that with home use, you'll just use the supplied software and all will be well except that there are other PVR solutions which replace the Hauppauge software but don't include either bootp or dhcp services hence it gets farmed out to something else and with no option to configure a static address you're pretty much forced one way or another.
