True, people are only now starting to get their AExps, but I've already heard a couple of reports of them not working well (or at all, in some cases) with regular AirPort cards (not AirPort Extreme). Is this true? On the AExp part of the Apple site, the tech specs section reads: "System Requirements For Macintosh Users Hardware A Macintosh computer with an AirPort Extreme Card or AirPort Card" That sounds promising, but the reports to the contrary have me worried. So those of you fortunate enough to have already received your AExps, do they work with the regular AirPort card? For a follow up question: can I get an AirPort Extreme Card? I've got the last generation of 15" TiBook - the best you could get before the aluminums came out. When I ordered it, there was no option for an AExt card that I remember ... otherwise I'm sure I would have gotten it. Regardless, it shipped with the regular AirPort Card, and I'm wondering if I'd be able (should I absolutely have to) to upgrade to an AExt Card. Thanks.
