I use it almost daily. :)

It'll save you wiring time certianly, but it does open you up to some
security issues as have been detailed on the list in other places.

Pretty trivial, actually.

802.11b runs at 11Mb/s, which is roughly 1MB/s. However, you'll likely
see it top out at 600KB/s, if you're lucky. Most inexpensive cards and
hubs/switches you can buy this days are 100Mb/s, so you've got an order
of magnitude difference in performance.
For most of what I end up doing with my laptop when its on my wireless
network this isn't an issue. (i.e. I'm not streaming uncompressed
video or something) And when surfing the net I'm limited more by
my 386Kb/s SDSL line, so that's an order of magnitude slower then my
And of course, the security thing which has been beaten to death.

Depends on how you're going to be using the machines on the network
mostly. I mostly use wireless to allow me and my wife to walk around
the house with our laptops. Our full machines are attached to a wired
network, if only for in-house high speed gaming purposes. (Although we
haven't played UT or Q3 in awhile.)
If you don't mind being stuck down in 11Mb/s land, you should be fine.
For most people and most applications, this isn't an issue.
