EVDO Rev. A (Up to 3.1 Mbps)
USB format with an interesting clip for keeping it out of harm’s way (looks a bit cumbersome though)
Smallest broadband card available today
microSD card (up to 32 GB expansion)
Supports laptops going into sleep and hibernation (i.e. it’ll connect after being woken up)
Unless you’ve already had a broadband card, the last feature may not matter that much. When your only way of getting online is a broadband card like myself, that becomes really important. It’s a nice feature that I hope to see become standard.
