I’m quite excited about the new MacBook and was thinking of buying one (my wife gave me permission), but they’re not shipping until next month, so I have some time to decide. A friend of mine mentioned to me today that the new machines have ExpressCard and not PCMCIA slots. A year ago I wouldn’t have cared, but I’ve been using an EVDO card (Sierra Wireless AirCard 580) on Sprint and have grown quite used to it. In fact, the WiFi coverage in the hotel is so awful that I’ve been using the EVDO card and even downloaded about 120 MB of updates. This card won’t work in the new MacBook and I haven’t heard any mention of an ExpressCard format EVDO card. If an adapter comes out, I’d be golden.To make matters worse, even when an ExpressCard EVDO card comes out, I want the ability to use an EVDO router such as the Kyocera KR1 which takes a PC Card. So getting an ExpressCard will not be advantageous to me. I guess I could tether my Samsung A900 to the router, but then I can’t use the phone when I’m online.So, I’m hoping for an adapter that lets me use a PC Card in an ExpressCard slot; I’m not sure it is technically possible, but I can always hope.
