I’ll admit that when I first heard about 3UK’s MiFi offering and similar devices from other mobile networks, I didn’t really see the appeal.

The tiny gadget – about the size of a typical candy bar phone – uses its own built-in 3G modem to create a mobile broadband-powered WiFi hotspot, which, optionally, several devices can connect to. In my experience, however, mobile broadband isn’t the quickest (not helped by the fact that I sit in front of a fiber-optic connected laptop most of the day), so it’s not something that I’d instinctively want to share. But…

Now that I’ve actually used the MiFi, I totally get it.

It’s not just about sharing a single 3G connection with others – though at times this could be a life saver – but the flexibility the MiFi offers through the ability to add mobile broadband to devices that aren’t compatible with a USB 3G dongle but that do have support for WiFi.
