These have indeed been very common back in the day, I'm still using a 2003-vintage 1.5 GHz Pentium-M 'Banias' Acer Travelmate 292LMi notebook using ipw2200 (and have two spare ipw2200 mini-PCI cards). Works still fine using v6.5.8-rc1 and WPA2PSK/ CCMP (sadly it does not do WPA3) and I do use it semi-regularly (running the latest stable- or stable-rc kernel of the day). While it would be nice to replace it with an ath5k based card (to get WPA3 support), the card isn't that easy to reach in the notebook, so it would be sad to see this go.

While I'll cope if ipw2200 goes away (giving me the impetus to replace the ipw2200 card with ath5k - or at least to use an ar5212/ar2414 ath5k or bcm4306/2 b43 32 bit PCMCIA/ cardbus card (inconvenient, with the antenna sticking out) until then), these have been so ubiquitous in their days that there will be quite a few surviving specimens around (and this one is actually still in semi-regular use with current kernels/ userland, not daily, but 2-3+ times a month, mostly for isolated firstboot configuration of various networking gear).
