A few things to remember for those with uncertain wireless support

1) Don't forget you can easily try Ubuntu and wireless devices on most x86 laptops in the Live CD mode before you install. If driving somewhere to buy a USB device, bring the laptop along. You might also be able to run a Live CD and try a USB wireless device on another machine in the store (ask for permission first!)

2) If there's a Mac laptop handy, OS X doesn't need any extra software installed to share the laptops wireless access out the ethernet port, allowing simple DHCP connections. Just go to the Sharing prefs panel. (add a hub or switch to share with several machines)

3) Instead of using a Mac, some routers with free open-source DD-WRT firmware installed can also act as WiFi clients giving access to machines plugged into the ethernet port(s). Older WRT-54Gs often turn up cheap at thrift stores etc. and are ideal. (some versions have more RAM than others, check the DD-WRT site www.dd-wrt.com/ for more info) It's a good way to add wireless to desktops.

4) ... and of course Ubuntu runs well in a Virtual Box virtual machine, an easy way to use it under OS X or Windows hosts with whatever net access those already have. virtualbox.org It's a particularly simple/clean free solution for Mac users, not disturbing OS X at all.
