I was invited to Showcase Nokia 2009 where Nokia launches the Nokia E55, Nokia E75, Nokia N86 8MP, Nokia 6710 Navigator and the Nokia 6720 Classic at ZIRCA, Clark Quay, Singapore.
The E75 is the exact clone of E51 just that it includes a slide out full QWERTY keypad. Thickness wise, it is not much thicker and it sports a 3.2MP camera. It is mean to be a scaled down version of E71. But personally, I will choose E71 over this anytime!
