Summary: We've been using the apple usb modem for about 2 months now and our only complaint is that it often won't connect on a managed account, but like I said above, that is probably more a problem with the OS (Leopard) than with the modem itself. On the non-managed account it works perfectly.
Pros: compact design, modem on hold feature
Cons: trouble dialing up on managed accounts (I'm still unsure if this is a modem problem or an OS problem)
Summary: The days of external telephone modems has returned, apparently because the majority of people buying a new Mac have moved from dialup to broadband Internet. A Mac-to-phone connection is still useful for automated phone dialing from Address Book and for fax send & receive.
Summary: I purchased two external USB based modems to try on a G4 Mac Mini, the Apple USB Modem (MA034Z/A) and the Best Data Smart One series Modem (56USBPMAC). Overall, the Apple USB modem is a winner. It is small, unobtrusive, and gets very good through put.
Pros: Size, style, performance.
Cons: Must be connected to a USB port on the computer, not via a hub.
Summary: Apple stopped putting internal modems in their newest computer. I have a MacBook that I take on vacation in Vermont where I don't have a wireless or broadband connection where I stay (although I can always get one nearby, there's nothing like having access RIGHT THERE where you're staying!
Excerpt: This modem was introduced by apple after the 56k modem was dropped from the October 12, 2005 Revision of the iMac G5. It is a combined 56 kbit/s data modem and 14.4 kbit/s fax modem which also supports V.92, caller ID, wake-on-ring, telephone answering (V.253), and modem on hold.
Summary: Siempre sentí curiosidad por estos modems USB. Teniendo en cuenta que Apple es garantia de calidad me lo compré. ¿El resultado? Estupendo. Es pequeño, liviano y podés conectarlo al puerto USB para poder acceder a tu línea telefónica.
Excerpt: Für den Notfall habe mich mir dieses Apple USB Modem zugelegt. Ich habe letztens gemerkt, dass ich meiner VDSL Leitung nicht blind Vertrauen kann und hatte ca. 12 Stunden keine DSL Verbindung. Die Telefonleitung hat funktioniert.
Pros: sehr funktionell, einfache Konfiguration über OS X
