Look and feel
With its smoked glass and chrome finish, the KF600 is a striking slider phone that’s well built, feels good and looks original. We also think the InteractPad user interface looks great, even though only a section of the screen is touch-sensitive.
Features
The InteractPad is a quirky feature that’s integral to the handset’s usability. Elsewhere, the feature set is distinctly mid-range. The three-megapixel camera is a plus, but the lack of 3G is a shame. Although the display is large and undisturbed by any unsightly keys, a good third is taken up by the virtual InteractPad.
Ease of use
For a touch-screen phone, the KF600 is easy to use, but it achieves this by mimicking a regular phone interface. As a result, you don’t get the large display benefits of other touch-screen phones. It’s still good fun though, and well thought out.
Performance
Aside from the slow data speeds for web browsing, the KF600 is a good all-round performer and the camera takes decent snaps.
Battery life
As with the feature set, the battery life is satisfactory without being overly impressive.
