According to London based Infonetics Research the sale of data cards are growing around the world. This is great for companies like iPass.
Now all they need is a 3G consumer play to go past the millions of enterprise customers who use their service for global WiFi roaming. GSM would be my preferred play, but my guess is given their USA dominance and the better build out of Verizon Wireless and Sprint EVDO networks that initially an EVDO play would be more appealing.
Why are more people turning to data cards? We're living in an always on, always connected world.
