No mention of WiFi or Bluetooth? That would tie it to EV-DO/CDMA, making it barely useful outside the Americas, or, given that Amazon seems to have some integrated device and data plan (there is no mention of it needing an extra SIM card and data plan), probably not even outside the US. Besides, EV-DO (much like EDGE, its GSM counterpart) is much less useful than 3G for internet access thanks to its large round-trip delays.
