I'm pleased you didn't have a problem. In my case, the laptop has been supplied by my institution, so I didn't have the luxury of doing the research on which card it has, and whether there is a Linux driver for it.
Your response is a common one. To me it sounds like you've just said: "Well, if you'd done something different then you wouldn't have problems." That may be true, but it's unhelpful for me.
Im guessing you have a Broadcom chip (it's very common and usually doesn't support linux), I think Ubuntu/the Linux community needs to focus on that. If the wireless hurdle can be overcome Linux would be much more common.
When I installed arch for my sister, the laptop had a broadcom chip. It kind of worked, but with very low signal strength. But the AUR had a package that fixed it, now it works perfectly...
