EE's 4G Kite device launches in the UK today. Don't panic about the size of that screen, it's not a phone. You don't have to look at Twitter on that. It's a MiFi personal hotspot thing to allow all your precious Wi-Fi things to work on the network's 4G network.
The Kite can be had for £69.99 on a PAYG basis, or attached to one of the network's 4GEE and 4GEE Extra plans for "free" as long as you commit to spending at least £15 a month on a data contract. [EE]
