RokAir: inexpensive WiFi USB adaptor for Mac

I think you meant adapter, not adaptor ;)

Both spellings are correct, actually. According to some sources, the -er suffix refers to a person that adapts, while -or refers to a device that adapts. But The Columbia Guide to Standard American English says, "Adaptor is an infrequent variant spelling of adapter. Neither spelling is attached exclusively to persons or to things."

Despite that, I think I've seen the -or suffix used more commonly in technical writing than the -er suffix.

Thank you jimothy for clearing it up (no sarcasm here, I'm often the resident Grammar Nazi here).

As for the subject at hand, I am curious what is the prospective market for a device that has rapidly dwindling potential user base (i.e. G3 and G4 Macs)?

Built-in Airport in all current Macs with screens (as well as the Mini) represent the majority of Macs out there; the remaining number is so small that I'm assuming the adaptor can be sold to Windows crowd as well, for the sake of the device maker.

I agree that the market can't be very large for these devices. I have a MacPro that was purchased a little over a year ago that I chose to not order with an Airport card. It would have delayed the shipping by almost a month and I didn't have enough patience for that:)

Since it works with Apple's Airport software I believe there is extra incentive to buy this one over other 3rd party wireless adapters. If it were me I would just get the Airport kit from smalldogs or another such store and do the installation myself. I don't need another USB port taken up.

Different brand, for my brother in-law who own a G3 iBook with no Airport card installed. For close to $150 on ebay for a used one $50 shipped was cheap.
