I have E169, Rob and Graham have E160e, Linda had E1762

"the E169 is rated at a higher speed 7.2 Mbps"
"The E160e is almost identical, except that it maxes out at 3.6Mbps, and the exterior is a little different."

"E1762 has much faster upload speed compared to the e169"
"E169 is only a HSDPA unit – does not support high speed uplink so is limited to 384k uplink... E1762 is a HSUPA capable device so can support (up to) 7.2Mbps downlink and (up to) 2Mbps uplink (possibly up to 5.76Mbps if/when firmware/service available)."
