| ReviewsDisplay Verdicts | 80 out of 100 The Register A well-equipped mid-range 3G mobile, delivering a decent collection of web applications in a distinctive design. read more 70 out of 100 TrustedReviews When it comes down to brass tacks, all that really marks the mid-range K660i out from other mid-range Sony Ericsson handsets is the quick access web buttons on the front fascia. And if you fancy 3 as your network then the distinctive colour scheme on offer is different too. read more 67 out of 100 CNET Asia There are more ticks than crosses next to the K660i, but ultimately this is a handset that fails to capture our imagination. HSDPA is nice, but it boosts the price of this phone well beyond otherwise similarly spec'd handsets, and we're not convinced that the younger market will be taking advantage of the speed. read more 65 out of 100 Good Gear Guide The K660i's Web shortcut keys are a nice touch.

The E51 is targeted as an entry level business smartphone, and in this class, it is simply unparalleled. read more N/A out of 100 GSMArena Nokia offers a wide range of Eseries business handsets, including Communicators and enhanced messaging devices of different form factors.
