The special offer is valid for one day only (Wednesday 13th February) and is available at O2 retail stores and online.
The standard £150 price point (O2 UK PAYG) already offers very good value for money compared to other Windows Phone 8 devices, but the one-day-reduction to £120 is even more attractive. It's not the cheapest Windows Phone device available, the Windows Phone 7.5 powered Nokia Lumia 800 and HTC Radar are both widely available for £99 or less, but, in our opinion, the Nokia Lumia 620 is the best Windows Phone device to buy, if overall value-for-money is your most important criteria.
The Nokia Lumia 620 has near-equal functionality-set to the high end Nokia Lumia 920 and HTC 8X. Inevitably, in order to meet the lower price point, cuts have been made to the hardware specification. In terms of the user experience the most important of these are the materials, screen size and quality, and camera quality. Like the Nokia Lumia 820, the Lumia 620 also has less internal memory that its higher end sister (8GB versus 32GB), but a microSD card slot is present, and a 32GB card can be purchased for around £15 online. Other specifications, such as the RAM, processor speed and connectivity options (no 4G), have also been cut, but these have only a relatively minor impact on performance and user experience.
