Before this phone I owned a Nokia 6230 and a Motorola SLVR L7, both international unlocked versions. Motorola phones like the SLVR and the RAZR are slick and feature-packed but they have a horrible interface, the non-US carrier supported versions are horrible to set up in the US and they lack a lot of features. Nokia is the opposite, nice user interface -possibly the best- but a downgrade in design and slickness. Enter the Sony Ericsson. This phone has everything: Feature packed, all the features work, easy to set up, friendly user interface and eye-catching looks. Before this phone I had an international version of the SLVR, which I use on the T-Mobile network and I was very frustrated with it (didn't recognize voicemails, only the sync feature worked with Bluetooth on my Mac, couldn't browse the Internet and some buttons were wasted on features not available in the US), no such problems with the W810i. It works with the network as good as any supported phone. The Walkman mobile interface works like a dream. I'm surprised by the quality of the pictures, which is similar to early Cyber-shot models. If I had to criticize anything about it would be the flash, which is not really a flash that goes off when you take a picture, but a light you turn on manually. I would have liked the lens to be covered for protection and hooking the headphones with a normal plug and not the Cell phone's proprietary jack. For the money, this is a phone that can almost replace your snapshot and your .mp3 player, so I consider it a bargain. It's also a cell phone that will make you stand out of the Motorola RAZR crowds, for those who consider a cell phone an accessory.
