We've had our eye on Sprint's EX720 mobile broadband card for quite some time now and the folks at SlashGear recently got the chance to take it for a test spin. Performance-wise, the card averaged impressive download speeds of 826 kb/s with upload speeds of 103 kb/s. It runs on Macs, but you'll need BootCamp or Parallels to activate the card via Sprint's Windows-only software. Here's the killer. Pricing. The card goes for $179 with a 2-year contract ($59/unlimited monthy) or you can do 1-year at $79/month (unlimited data).
