Looks like a mouse, but the small size makes it a lot more convenient (my router is more than half a foot long and has to share a small space with my modem).
Sorry for the idiotic question but...are they saying that this uses your cell-phone's 3G as a way around hot-spot restrictions, or that this device has it's OWN 3G connection (and thus would require for you to get separate service from your carrier)?
