Three UK's third generation MiFi has slightly more refined looks than its predecessor, but it doesn't feature "go faster" stripes which is curious as the inclusion of HSPA+ technology promises a turbo boosted Internet connection with speeds theoretically up to 21 Mbps - enough to put many landline broadband connections to shame. I attended the launch event for the new MiFi (also known as the Huawei E586) and have been trying one out. How does it perform? How easy is it to use? Plus, with the increasing number of mobile phones that are capable of tethering (sharing their mobile broadband connection with another device through WiFi) is it still a compelling product?
