You can’t have the headphones plugged in and charge the phone at the same time though as the two connectors share the same socket on the bottom of the handset.
The Memory Stick Duo slot is on the top edge of the casing, making it easy to get to for card swapping. Unfortunately, Sony Ericsson only sees fit to bundle a 32MB card with the phone. With just 16MB built-in you are going to need to invest in more memory to have any chance of using this phone as a portable music player.
There is software for both entertainment and keeping organised built into this phone. There’s Photo blogging, VideoDJ, PhotoDJ and MusicDJ for editing media and the quite hilarious FaceWarp, which applys ‘humorous’ twists to photos – great for when your sitting with your mates in the pub.
Other software includes a calendar, task manager, alarm clock, calculator, note taker, stopwatch, timer and sound recorder. The Web browser is supplemented by an RSS feed reader. Email, MMS and SMS are of course all catered for, and Bluetooth and infra-red are both built in. The phone will send stereo to a suitable Bluetooth headset.
You get a USB cable for PC connection and the PC Suite software for sharing data with a PC including synchronising diary and contacts. Alternatively you can use the phone in USB Mass Storage mode if all you want to do is copy files between it and a PC.
The camera flash can be set to stay on indefinitely or for one minute to act as a torch, or used in an SOS configuration (three long and three short flashes continuously).
There’s plenty of choice right now in the music phone market, such as the already mentioned Nokia 5300 XpressMusic and the very tiny Samsung SGH-X830, both of which have some good music control features. The W850i doesn’t beat either on size and sits midway between the two on battery life but it’s the only one that has 3G, which could swing it for some.
