(Nearly) full tickless operation in 3.10
Now, how often do new -stable kernels come out?
Reboots for new gadgetry would be a small proportion of the total number of reboots you have to do anyway.
Quotes of the week

I've plugged at least three new (as in, this computer hadn't seen them before) gadgets since my last reboot 227 days ago. (TASCAM external ADC, a TI DSP EVM and a USB-to-serial cable.) And those are just the three I remember. I don't remember if I plugged my wife's phone in or not, for example. One of these days, I'll be moving the scanner over to my computer, and I know my machine hasn't seen it before.
I try to reboot at most 1 - 2 times a year at most, once my system's stable.
And it doesn't have to be that you bought the gadget new. It has to be a new-to-this-computer gadget that doesn't have the appropriate driver. "Hey Mom, before you leave, can I grab that photo you took of the two of us off your camera?" *plugs it in* "One moment please. Now reboot." If I happen to upgrade before the next time she visits... am I up for another such reboot?
I guess that brings up a second question: Would you retain the list of drivers you've "faulted in" so that the next time a vendor sends you a security patch, or the next time you upgrade your OS, you don't have to re-fault in all your gadgets? And is there an option for a batch mode? "Thank you for installing LatestShinyDistro overtop of LostItsLustre Distro. Find everything you own that you'll want to hot-plug into a USB port, and I'll go build you a proper kernel. Press enter when done." Uh, no.

I trust everyone that uses my private network (my wife and a couple friends).
Sure, someone *could* try to hack my WiFi and then try to find a remote root vulnerability that doesn't require an open port, and then try to guess my 8 character randomly generated alphanumeric password, but really, I'm not too worried about this machine.

Those of us with friends and colleagues often have requests to plug in random bits of equipment for some quick something-er-other. Having to wait for a recompile and a reboot certainly would make people "nostalgic" for Windows (which does not require that kind of crap, hasn't for many many years, and only the odd driver with an idiotic installer script even asks the user to consider rebooting these days).

In fact, Windows does rather better than Linux does in this regard in that it's possible to replace the graphics driver for a running system with little more than a quick flicker.
In Linux you *still* need to restart X, which in practical terms is not much different for the desktop user than rebooting.
(I'm hoping dynamic reconfiguration is something that Wayland will improve upon, if it really gets off the ground)
