old tech? new tech? worth the duckets? Sony Ericsson Introduces New Quad-Band EDGE / WiFi Combo PC Card

Am considering an EDGE-enabled wireless card as a new option for more reliable data connectivity via my mobile devices...can also throw it into my laptop (or anyone else's), which could prove useful in certain situations....

question is, is there something better available today? 6 months from now? on the horizon? ...sigh...the slow pace of innovation in the domestic wireless data market (3g, 4g, and beyond) continues to drive me loco.
