In Tesco this morning I noticed the Nokia Lumia 510 on offer for £70.

Quick spec: Windows Phone 7.5, 4″ display, 800 x 480 screen, multipoint touch screen, Bluetooth, Wi-Fi, GPS, 256MB RAM, 4GB storage, 5MP camera, 480p video camera. Full details here.

256MB is minimal these days and there is no SD memory card slot or front-facing camera. For battery life, Nokia quote 653 hours of standby or 8.4 hours talk time on a 3G connection.

Sill, at £70 Windows Phone is no longer an expensive option.

If you want Windows Phone 8, you can get the Lumia 520 for £99.95 on Orange pay as you go, according to Nokia’s chart.
