Photos: Hands-on with the Sony Cyber-shot W170 and W150

There'll presumably be no sibling rivalry between the equally famous, and equally annoying, Monica and Gabriela Irimia -- otherwise known as the Cheeky Girls -- or Sam and Amanda Marchant (Big Brother irritants and pop-flop duo Samanda). They can all enjoy this 69mm (2.7-inch), 230,000-dot LCD screen.

The W150 is pictured above on the W170's screen. As you can see, the mode wheel, clickpad and optical viewfinder are all identical. The difference -- huzzah! -- is that while the W170 boasts 10 megapixels, the W150 has 8. As a result, it's twenty quid cheaper at £156. Is there a difference in quality and value? Stay tuned for our in-depth reviews to find out.
