As the title, what's the best and the worst phone you've owned? Best The best phone I've ever had has to be the Sony Ericsson W800i. The W800i was the Walkman version of the K750 and when I was buying it I had a choice of the two and went with the W800i. I didn't regret it as served me very well for many years. It had a memory card slot but it took a memory stick pro duo as opposed to the microSD's around now. Towards the end of having it the middle "joystick" started to stick a little and the plastic protective covering over the screen came away but it still worked brilliantly. In the end I changed it and was sad to see it go. I think I ended up exchanging it for another phone Worst I'm a great fan of Sony Ericsson/Sony phones, but the worst phone I've had was when they first started doing their slide phones. I had the W580, actually I had a lot of them, and they all were terrible. The screen connections were very flimsy so even if you so much as patted it in you pocket the screen would become broken. This happened with the first one I had within a couple of hours of having it. I changed it every time it happened and I must have had 4 to 5 new phones within the space of two months. In the end I didn't change it and bought a Samsung slide phone instead.
